What You Need To Know About Concrete Cracks in summer

Concrete cracks happen to be a common issue, specifically in summer. Homeowners usually misunderstand concrete cracks assuming they bought low-quality premixed concrete. Hire professional concrete suppliers in QLD Brisbane to guarantee high-quality concrete.

What Causes Concrete Cracks in summer

Concrete cracks are an issue that unfortunately cannot be avoided, especially in summer. Even high-quality premixed concrete might show some micro-cracks in summer. In summer, the concrete cracks appear when the excess heat reaches the earth’s surface, leading the soil around the house to shrink and pull away from the foundation. Soil shrinkage results in foundation movement making the small cracks bigger and might grow beyond an inch depending on the extent of soil shrinkage.

With time, the cracks weaken the concrete leading to sinking or settling of the slab foundation. You might realize the foundation is no more extended level in worse conditions and even notice some sloping.

Homes Built on Clay soil are Prone to Concrete Cracks

Clay soil will swell naturally when it becomes wet. In summer, the clay soil shrinks as it dries owing to the hot temperatures. The shrinking and swelling appear at ground level, pressuring and pulling on the foundation of your home. Hence, the shrinkage leads to concrete cracks, and eventually, structural damage. As a result, it helps if you extract the clay soil completely and replace it with rocks to avoid concrete cracks.

Plants Growing Near Your house could Cause Concrete Cracks

Another reason why concrete cracks appear is due to the roots of the plants growing next to your property. Hence, remove the trees and other plants known to have roots spread widely beneath the surface. It must be noted that even the seemingly small plants could cause cracking in your concrete.

Watch out for Concrete Cracks in summer

The hot weather is not the only cause of concrete cracks. The wet weather might also have an effect, causing cracks in your concrete. Hence, no matter the weather or season, cracks can appear on the foundation. This is why it is crucial to inspect your property for concrete cracks all-year-round. If you notice concrete cracks, hire an experienced professional to examine the cause and recommend a solution.

How to avoid concrete Cracks in summer

Concrete cracks could be a problematic issue, specifically in summer. Here are some significant recommendations to avoid summer concrete cracks.

  • Watering around the concrete foundation during summer droughts prevents shrinkage – keeping the water level consistent throughout the year.
  • Protect your foundation against excess moisture by using high-quality waterproofing
  • Ensure your landscaping does not endanger your concrete slab. Therefore, get rid of plants growing next to your property.

Conclusion

Hot weather is one of the reasons you might experience concrete cracks. Nevertheless, it is not the only cause of concrete slabs to crack. Ensuring you source premixed concrete from experienced concrete suppliers assists in preventing concrete cracks.  Moreover, practice the tips I have outlined above to help you prevent concrete cracks.

Engage an experienced professional for advice on the coarse aggregate and site dimensions. Through this, you are set to enjoy the best experience from your concrete suppliers.

Concrete is only as strong as the steel you put in—Find Out Why

Concrete is strong against the forces of compression. Nevertheless, concrete has low tensile strength as well as flexibility. Hence, engineers recommend the use of steel reinforcing mesh while building concrete slabs. Engineers and professionals in the construction industry rate reinforced concrete as a ubiquitous building material. If used alone, concrete is quite brittle when compared to your expectation, hence, it is hardly useful in constructing properties. A steel bar makes the best reinforcement when building as it bonds well with concrete. Also, its expansion and contraction due to temperature changes are similar to that of concrete.

Hence, one of the causes for choosing steel is its significance in the property’s structural architecture. Steel suppliers stock two types of steel bars utilized in construction. The type of steel to use on your property depends on the application. Here is an overview of the types of steel bars available in the market today.

1.   The Mild Steel Bars

The mild steel bar is plain on the surface and features round sections with a diameter of about 6 to 50 millimeters. This kind of steel bar comes in long length as it can be cut quickly and bends easily without causing damage.

2.   High Strength Deformed Steel Bars

The high-strength deformed steel bar features lugs and ribs, or deformations on the bar’s surface, to enhance the concrete bond. These are usually twisted to strengthen the bonding with concrete. The structural engineers prefer cold twisted bars for use in constructing properties.

Hence, purchasing steel bars, explain the steel suppliers the intended use to avoid inconveniences. Trusted steel suppliers would listen to the customer keenly, making sure that they supply the right type of steel bars for your construction.

What to Check When Purchasing Steel Bars

Purchasing construction materials might appear overwhelming, specifically if you are a newcomer. In that regard, you must research further to avoid purchasing low-quality steel bars. Here are important considerations you might want to check when buying the steel bars.

  • Talk to the structural engineer for recommendations of the right steel bar for your construction type.
  • Only purchase the grade of steel bar prescribed in the drawing or the list given by the construction engineer.
  • Check the bars’ identification mark to ensure you are purchasing steel bars manufactured by experienced professionals.
  • Talk to your steel suppliers for the best steel bar brand recommendations available in your region.
  • Check the steel reinforcing mesh for rust films. There must not be any rust film on the steel bars.
  • Use the vernier caliper to check the diameter of the steel bar.
  • Avoid purchasing steel bars from the companies through rerolled or scrap metal as the raw materials. These are likely to have higher carbon content and are prone to corrosion.

Conclusion

Steel bars are a critical component when constructing through the use of concrete. Never be duped into using concrete without applying the steel reinforcing mesh. Steel and concrete bond is integral when laying slabs. Always source concrete from professional steel suppliers near you.

A Quick Step by Step Guide to Install Interlocking Concrete Blocks

Interlocking concrete blocks have been trending for quite some time now and have acquired an easy entry to driveways and yards. Not only is space intensification a benefit, but concrete prices Brisbane are affordable as well and are a worthy alternative to consider for your home renovation project. So here is how you can kick start the process of interlocking cement blocks:

Finding out the right size

Prior to starting this project, you must determine the size of the blocks that you will be utilizing for your floor. Measure the area where you will be laying the blocks and as per the measurement decide the size and thickness of the block that suits your budget.

Marking the territory

Once you have got all the staples from concrete and steel suppliers Brisbane, next, you must trace the area where you are most likely to place the blocks. Check for any gaps, inconsistencies, or holes in the marked area so that you can fill up prior to the installation of the concrete blocks.

Digging the Earth

Afterward, you must dig out the soil according to your desired depth and make sure if there are any remains or lose pieces while you unearth. A six-inch depth unearthing is considered to be an ideal requirement for holding soil and gravel, whereas a 2-inch depth is apt for driveways that must be installed with concrete blocks.

Laying of sand

After the digging process, the sand bed is spread on the surface, which is further leveled and smoothened to make it ready for establishing the new base. You must ensure that you utilize an equal quantity of cement towards both the grout surfaces to make sure an even finish; often, the mixture is taken to be one inch in depth. This step must be taken with proper care because a strong reinforcing mesh Brisbane base is needed to make the blocks stay fixed at their respective place.

Installation of edge restraint

Thereafter, an edge restraint must be installed to terminate any type of movements that could arise because of the sand bed and concrete blocks. The edge restraints are available in several alternatives ranging from molded restraints, concrete restraints, rigid edge restraints, and much more, which could be picked up according to the users’ choice.

Fixing interlock blocks

Moreover, you could get started with the layering of interlock blocks according to your desired pattern. You could consider devoting more time to this process to obtain a perfect block alignment.

Removal of edges

Once you are done laying down the blocks in a certain pattern, you could consider cutting the edges of the concrete blocks in order to boost the aesthetics of your project. This will not only aggrandize the looks but will also make the blocks appear dapper, clean, and seamless.

Vibrate

Now, once you have completed all the above-mentioned steps, you must roll out a sand layer on top of the pavers. Afterward, you can utilize a vibrating plate over the surface to turn the interlocks between the blocks strong. The excess sand can be swept inside the holes to fill it.

Conclusion:

Consider buying staples from concrete suppliers Brisbane and choose an interlock cement block floor and sit back and witness how your home improvement efforts are intensified quickly.

Effective Tips to Prevent Concrete Cracks

Concrete Brisbane has already become a trustworthy, long-lasting, and cost-effective construction material. Despite possessing these qualities, concrete still remains vulnerable to several kinds of damage and one of the common of these is cracking. Cracks in concrete occur due to several factors. When concrete bears excessive weight, it may break concrete or shift the soil under the slab. Erosion can subsequently lead to cracking in concrete. It is also important to consider that not every kind of soil is perfect for working with concrete. The soil should not have any moisture and should be free from tree roots.

Here are some tips on how you can prevent concrete cracks:

1. Bring down water content in concrete

When there is a low water to cement ratio, it will improve the quality of concrete. The ratio can is the weight of water to the weight of cement used. When there is a low water to cement ratio, it will lead to strong strength in concrete and reduced cracks. It is ideal to maintain less water content as it will boost the robustness of concrete. Concrete tends to expand and shrink as temperatures change. The major tendency of concrete is to shrink. Shrinkage has emerged as the root cause of cracks in concrete. As concrete begins to harden, it will evaporate excess water and shrink. Therefore, if the water content is low, shrinkage will also remain low. You should remain aware of the concrete prices Brisbane.

2. Effective curing of concrete

It is imperative to prevent the fast loss of water from surface or concrete drying as it may cause excess drying of the slab. It is advised to cure the concrete slab for many days. You can cover the concrete slab with cotton mats soaked in water. You may also opt to spray on curing compound as it can effectively prevent water loss. Never subject concrete to heavy weights during the curing phase. The curing phase can last for up to a month. You must strengthen your concrete with the correct curing product. Curing agents can effectively produce smooth, flat, and long-lasting concrete floors.

3. Effective placement and vibration

If you have an effectively placed, vibrated, and finished concrete, it will diminish the possibilities of generating cracks. For the right placement and vibration, you should contact concrete suppliers Brisbane.

4. Effective compaction of soil

Proper compaction of soil is crucial to eliminate settlement cracks in concrete. The area of the concrete slab should be compacted as this will prevent settlement cracks in concrete later on. If you leave the soil loose, it will settle over time and may produce cracks on the surface. This is as applicable in home renovation as it is for construction on the highways.

Conclusion

The aforementioned tips will certainly go a long way in preventing concrete cracks. You can procure top quality steel from leading steel suppliers Brisbane at economical prices. You can avoid concrete cracks by selecting top quality cement mix that will react in the best way with accurate water content. And, the cement mix should contain a solid and dense aggregate to bring down shrinkage risk. You should avoid products that will include dirty aggregates and accelerators as they may enhance concrete shrinkage.

3 Common Reasons for Concrete Cracks and What to Do About It

Concrete cracks are a very common household problem but are often misunderstood. Whenever a property owner finds a crack on their new concrete, they often assume something is wrong with the concrete or a bad quality product was used. But this is not applicable at all times. Some of the concrete cracks found are inevitable. You can hire the best concrete suppliers Brisbane to do the job of building a house but even with the best plans and designs, concrete cracks cannot be avoided.

Why Concrete Cracks?

Now you must be thinking, why do concrete cracks form? Here are the 3 most common reasons.

1. Rapid Drying of the Concrete

Once the concreting is done, the rapid drying of the wall or slab will notably increase the chance of cracking. The chemical reaction that causes the concrete to settle from the liquid state to a solid needs water. This reaction happens for several days and weeks after you pour the concrete. If it happens too quickly, cracks may appear.

2. Excess Water While Mixing

Usually concrete does not require a lot of water to achieve maximum strength. Often concrete used in residential work has too much water added to the mixture at the construction site. The more water you add the easier it is to install. But as the concrete shrinks and hardens, the water is evaporated causing a crack on the concrete wall. The wetter the concrete is the greater the shrinkage will be.

3. Lack of Control Joints

Control joints help prevent concrete cracks. The joints should be of the slab and no more than 2-3 times the thickness of the concrete.

Types of Concrete Cracks

Listed below are the 4 common types of concrete cracks:

  • Hairline crack
  • Shrinkage cracks
  • Settlement cracks
  • Structural cracks

What to Do About the Concrete Cracks?

Discussed below are some ways you can avoid concrete cracks:

  • Modify the concrete mixture: Contact premix concrete Brisbane experts for a better understanding of the ratio of the water and concrete. Be sure to choose a reputable contractor who knows the proper mixture ratio.
  • Allow more time for curing the concrete: It takes about a month for the entire curing. When waiting for the concrete to dry keep the following time in mind:
  • 24 to 48 hours, 7days (partially cured), and 28 days (fully cured).
  • Good quality concrete: Now concrete is available in different strengths and prices. It is very important to do some research before you finalise the concrete strength type with your contractor. Consult with few contractors and choose the best option suitable for you.
  • What lies below concrete: A foundation of a building is important and in the same way the soil support system beneath the concrete slab is also important. Start with a sound substrate and uniform support before pouring the concrete. You can also contact steel suppliers Brisbane for good quality products.

Bottom Line

In general, cracks can happen for a number of reasons and not always because of bad quality concrete. Cracks that are bigger than a credit card when running through the depth could be a sign of serious problems. You can consult an engineer or reinforcing mesh Brisbane expert to get the best repair solution.

Identifying the Need for Reinforcing Mesh in Concrete

As essential as construction is, it can also be a confusing field for novices. But what we all definitely know is that concrete is an essential component in almost all construction projects. This simple material allows us to create sturdy and strong buildings with ease. However, some projects have requirements that Brisbane concrete  alone cannot fulfil. This is where reinforcing mesh comes into the picture.

But what exactly is it? Who should or shouldn’t use it? Let’s take a better look.

What is reinforcing mesh?

A steel reinforcing mesh is made up of steel wires welded together in the form of a flat grid. There are many types of meshes used in construction (like carbon and fibre), though steel mesh is the most common and cost-effective. A reinforcing mesh comes in varying sizes, depending on the needs of the construction and the concrete slab size. The most common size is 150x150mm with a 4mm thickness.

A reinforcing mesh is set inside the concrete during construction. After the slab is set, the mesh inside it offers additional strength against pressure. Thus, concrete with reinforcing mesh is able to withstand much more pressure than regular concrete slabs. Contrary to popular belief, a wire mesh does not rust inside the concrete. This is because the curing of the concrete seals it completely by cutting off the oxygen that makes rusting possible. A reinforcement mesh is cost-effective on concrete prices Brisbane and prevents premature cracks in the concrete.

Another alternative to reinforcing mesh exists in the form of reinforcing bars (or rebar). Rebar is steel rods that serve the same purpose as a mesh. In most construction projects, both rebar and meshes are used together. Like the mesh, rebar also comes in variable sizes.

Who needs a reinforcing mesh?

A reinforcing mesh, while very useful, is not required in all constructions. It is important to understand where would you do and don’t need it. Most residential projects do not require a reinforcing mesh. This includes garages, pathways, and shed floors. If your driveway doesn’t see much traffic, you likely do not need a mesh either.

Larger projects that are likely to see heavy pressure need reinforcing mesh. This includes buildings, bridges, etc. Sometimes, a large project might not witness uniform pressure. In such cases, the engineers can identify the areas that need reinforcement. Some locations might just need extra reinforcement due to the age of their primary material (like old public buildings).

Even in small-scale projects, there is no one-size-fits-all solution. Sometimes, the ground below might be soft. In this case, using reinforcing mesh would stop the mini concrete from sinking. Sometimes, you just know that your small construction will be under a lot of pressure (like a garage filled with heavy vehicles). In such cases too, using a mesh is a good idea.

Conclusion

Construction is like building your dreams into reality. And we all want our dreams to be strong. Using the right steel reinforcing mesh Brisbane in the right place would help your build something that lasts a long time.

Different Proportions to Consider for Concrete Mix

As your construction project progresses smoothly, it’s quite important to consider the right concrete mix proportion. But, as the slurry gets prepared with the addition of cement, sand, and water, the ratio totally depends on the construction project. However, based on prior experience, the building codes offer standard ratios for onsite construction. If you are worried about quality, then you should opt for premix concrete in Brisbane from Reocrete. But, if you are not sure about the ratio, then you should read ahead to learn more about the proportions.

Materials used for preparing concrete

Among the basic materials, concrete always has cement as one of its constituents. While shale, limestone, and other ingredients are burnt to form clinker, the grinder grinds lump to obtain a fine powder. You may come across blended cement at some sites however, this is ideally used for masonry work, ideally for plastering. Apart from cement, aggregate and sand are also major constituents. The ingredients not only enhance structural integrity but also increase compressive strength.

Different types of proportions

  1. Nominal Mix ratios: Many years ago, the ratio of the constituents for concrete was actually based on the amount of cement and aggregate. Since this was considered a fixed ratio, such types of ratios were known as nominal. Ideally, the nominal ratio is 1:1.5:3 for M20 grade concrete and 1:2:4 for M15 concrete.

  2. Standard Mix ratios: As the contractor may vary the nominal ratio, the overall constitution may differ to some extent. Even though the ratio may enhance strength, the cement may not be suitable for the onsite construction work. Hence, in order to maintain minimum compressive strength, concrete is based on a standard ratio. While you purchase concrete, you may come across different grades like N20, N50, N32, and N25. But, for grades more than 50, the contractor may require special class concrete for the work. Regardless of the concrete mix, every grade is different with respect to its compressive strength.
  3. Designed Mix Ratio: When dealing with a Designed Mix Ratio, an experienced professional determines the precise proportion of the constituents. Moreover, concrete suppliers in Brisbane may follow a rational approach to figure out the proportion with the unique characteristics of the materials. It’s completely normal to use standard or nominal mixes for short-duration jobs. The ratios, in this case, don’t matter when there isn’t any need to carry out control testing.

Finally, for increasing the strength of hardened concrete, it’s important to maintain the water to cement ratio; fine aggregate can be added only when the person is preparing a sticky mix.

How to Determine the Tensile Strength of Concrete

When a contractor plans to execute a construction project, it’s important to firstly determine the overall strength of the concrete. Due to various effects and the applied load, the structures built from concrete are prone to tensile cracking. But, on the other hand, it’s advisable to use steel reinforcing mesh Brisbane when the contractor needs to reinforce concrete slabs. So, let’s get into two different kinds of tests and the procedure of measuring the tensile strength of concrete.

1. Split-Cylinder Test

A split-cylinder test is known as a standard test, which enables the contractor to find out the tensile strength indirectly. As the expert starts off with the test, a concrete specimen dipped in water is placed between the loading surfaces of the testing machine. While the load is applied uniformly along the diameter, the testing machine is set to a range between 0.7 to 1.4 MPa/min.

It’s important to note that a plywood strip has to be placed on the lowermost plate. Moreover, the expert shouldn’t forget to place another strip above the specimen. Later, the pressure needs to be applied relentlessly until the concrete specimen starts cracking along the diameter. At this instance, the expert has to record the reading which is nothing but the breaking load. He then has to use a formula for calculating the tensile strength of the specimen. Typically, the tensile strength may lie between 1/8 and 1/12 of the compressive strength. If you’re using mini concrete Brisbane, then you should be mindful of the time for which the specimen is exposed to water.

2. Flexure Test

The flexure test is yet another test that can help you determine the tensile strength of concrete. Before proceeding with the following steps, first pour fresh concrete into the moulds to create samples. Rather than coming up with just one sample, create three specimens for the test. Keep the hardened concrete in the water at a temperature between 24 and 30 degrees Celsius for two days.

After the specimen undergoes curing, it has to be placed carefully between the loading points. After some time, a load equivalent to 2% to 6% of the ultimate load has to be applied steadily. Mesh reinforcement Brisbane is essential for concrete slabs at the construction site.

Towards the end, as soon as you calculate the loading rate, find out the modulus of rupture. This figure is nothing but the extent at which the concrete cracks when it is subjected to continuous load or pressure. Post test, set the testing machine to a configuration for cylinder testing. Also ensure you discard the specimen and clean the testing machine thoroughly.

Once you have decided on what type of concrete you need, you can find suitable tools online. If you are concerned about completing the construction project, you should contact firms dealing in concrete delivery Brisbane  such as Reocrete Brisbane.
