Rebar: Steel Reinforcement for Concrete Structures

Rebar (short for reinforcement bar) also known as reinforcement steel are steel bars or mesh used on structures made of concrete, brick, and other types of materials to reinforce them and give them strength. Concrete has very weak tensile strength (ability to withstand load) and therefore requires reinforcement bars and meshes to enhance their strength and prevent the concrete from cracking.

The ultimate strength of a concrete structure depends on the reinforcement material used and it is very essential that you consult experts in steel reinforcement mesh Brisbane for a suggestion.

Why do I need to use Rebars?

Concrete has brittle properties and over time it tends to crack. Moreover, due to varied climate conditions, concrete tends to expand and contract and thereby causes tension, resulting in a collapsed structure. Adding rebars and steel reinforcement mesh helps the structure to absorb and distribute the tension.

What is steel reinforcement mesh? How is it different from rebars?

Steel reinforcement mesh and rebars serve the similar purpose of providing concrete with tensile strength. Steel reinforcement mesh is nothing but a wire mesh made out of individual rebars. Although they serve a similar purpose, the choice depends on the structural needs.

Which is better – rebars or steel reinforcement mesh?

Both are useful and often the choice depends on the structure itself. For example, rebars are best used vertically while steel reinforcement mesh is better suited for slabs. Also, steel reinforcement meshes have the ability to shape the concrete structure, which rebars do not have.

To best understand what type of reinforcing will suit your building, consult an expert on reinforcing steel bar Brisbane.

What are the available types of Rebars and steel reinforcing mesh in Brisbane?

Rebars come in various sizes, types, and technical specifications. The correct and suitable rebar type depends on various factors including the structure to be reinforced, the use of the structure, climate conditions and so on.

Generally, rebars can be divided into the following types:

  • Size: Based on the diameter rebars can be of 12mm, 16mm, 20mm, 24mm, 28mm, 32mm, and 36mm.
  • Shape: Rebars generally come in three shapes/cross-sections – deformed ribbed bar, round/plain bar and deformed indented bar.
  • Ductility: Based on the ductile strength it can be of low ductility, normal ductility or seismic (Earthquake) ductility.
  • The material used and coating: Based on the material and type of coating there are a handful of rebar types – European rebar made principally of manganese, carbon steel, galvanized, epoxy coated, glass-fibre-reinforced-polymer (GFRP), and stainless steel.

Which rebar should I choose?

The choice of rebar is determined by the Building codes and engineering specifications. Moreover, these specifications also determine the placement, spacing, pouring technique, and curing time for the reinforcement. Due to the multitude of types of rebars and demanding specifications, the choice of rebars and reinforcement is better left with the experts in steel reinforcing mesh Brisbane.

How to properly install rebars and reinforcement mesh?

Reinforcement installation is a highly technical job and must be done by professionals having specialization in reinforcement techniques.

Poorly installed reinforcement mesh and rebars can cause damage to the structure and may even cause the structure to collapse under tough conditions.

Some examples of poor installation are:

  • Using little or no steel in the concrete structure.
  • Improper placement of rebar resulting in the rebars too close to the edge and resulting in rust and corrosion.
  • Rebars and mesh shifting position when concrete is poured resulting in compromised strength.
  • Using low quality or wrong specification of rebars and mesh.

Overall:

Choosing the right type of reinforcement and proper installation is a highly complex process and must be done by a qualified professional and under the guidance of experts in the field. For any type of consultation regarding rebars and steel reinforcing mesh Brisbane, trusts none other than Reocrete.

Exposed Aggregate – Three Ways to Expose Aggregate in Concrete

Depending on the quality and type, the concrete prices in Brisbane range somewhere between $50 and $90 per square metre. In many cases, the design of the concrete determines its price.

To give an eye-catching appearance to concrete, contractors in Australia try out different kinds of exposure methods. On average, these methods correspond to the appearance and size of a project. Regardless of these factors, they tend to embed the majority portion of the concrete exposing only the top portion of the stone.

Here are the three popular methods that contractors use to aggregate concrete:

1. Brushing and Washing:

This is one of the conventional methods which do not involve the use of either special tools or chemical retarders. The rationale behind this method is to expose an aggregate to its anticipated depth. Most experts in the industry call it a simple method as it only necessitates the use of water and broom. By and large, this method depends on the time factor.

This method is suitable for small jobs and should start immediately when the surface motor attains the condition where one can remove it easily. The best way to figure it out is to scrub away a small area on the surface of mortar with a stiff nylon bristle broom. Because this method is neither cost nor labour significant, it is considered ideal for resurfacing mini concrete in Brisbane.

2. Using a Surface Retarder:

The removal of the cement paste is of utmost importance to resurface concrete. That said, most contractors prefer to remove it after at least a day’s time. For this purpose, they often spray a chemical surface retarder immediately on the surface of a slab. Aside from providing a greater degree of flexibility, it also makes the method suitable for larger uses.

More often than not, the use of a chemical retarder comes to the fore at the time of resurfacing premix concrete in Brisbane. A contractor may either use pressure washing or scrubbing while employing this method to coat a concrete surface.

3. Abrasive Blasting (ideal for lowering concrete prices in Brisbane):

There is an additional method for those who look for options that correspond to lower concrete prices in Brisbane. Abrasive blasting, also known as shot-blasting or sandblasting is one such method. The usefulness of this method is a contentious issue among experts, though.

The method is applicable when concrete becomes hard. The reason a majority of contractors do not consider using this option is that it poses the danger of fracturing the aggregate. It also reduces the shine of the surface, thereby making it appear plain and dull. One should avoid using this method if one wants to resurface concrete with the aim of retaining the full colour and shape of an aggregate.

Final Thoughts:

Just as the morning shows the day, the exposure of a piece of concrete plays a key role in the appearance of a concrete structure. And the method which a contractor uses to expose concrete has a bearing on concrete prices in Brisbane. So, it is a good idea to find out the method of exposure before making the final call on buying concrete to raise a concrete structure.

Concrete or Cement – What IS the Difference?

In the world of construction, two words are used quite often – “concrete” and “cement”. Most people assume that they both refer to the same thing, but this couldn’t be more untrue. Though both cement and concrete are used in the same field, they are different materials used for different purposes. Let’s find out the differences between the two.

What is Cement?

Cement is just a small component of concrete, usually comprising 10-15% of concrete. Cement is basically the glue of any structure, which hardens and gives it a firm shape. Most of the cement varieties used today are hydraulic in nature, including the common Portland cement. Upon coming in contact with water, the cement hardens permanently. The process is irreversible and can occur even underwater since the amount of water present makes no difference to the chemical reaction. Apart from concrete, cement is also used in brick walls.

What is Concrete?

Concrete is the most common material used in construction, akin to building blocks. Premix concrete is composed of various materials like aggregates and paste. The aggregate is made up of smaller materials like sand or crushed stone, while the paste is a mixture of cement and water. A concrete mixture is made depending on the properties like strength and slump, which is why concrete suppliers Brisbane ask the specific purpose for using the concrete. It is then molded into different shapes and used for various construction projects.

While dried cement is the last stage for the material, dried concrete is only halfway there. While both concrete and cement form integral parts of construction projects, it is important to remember the difference between the two.

Budgeting your renovation, from the scope to concrete prices

Concrete prices, the amount of concrete you need, and how you can afford to pay your trades are some of the practicalities that come with renovating. Building and renovation projects are exciting and some people might’ve ‘caught the bug’ after watching the reality shows on TV. Programs like The Block, House Rules and Reno Rumble, though entertaining, only offer a snapshot of what a project is like.

Starting the project is a commitment in itself, especially for first-timers. Buying the property and doing a walkthrough causes a mixture of excitement and intimidation. But that walkthrough and subsequent visits will give renovators an idea of what needs to get done right away. This is called ‘scoping the project’.

Scoping the project includes setting out the initial budget. It’s important to be transparent with your builder and contractors about your costs and what you can afford. What you want won’t always translate financially. NAB recommends budget calculators to keep you honest and track what you spend.

Getting quotes is the logical next step. Reocrete provides on-site delivery of Readymix Concrete. We also provide steel mesh, which is an essential component to any concrete slab. Our concrete prices depends on how large an area you need. The business is family-owned, friendly, and competitive on price. Our combination of steel mesh, concrete delivery, and even on-site storage makes us your one-stop-shop for a major component of your renovation. Our quotes are delivered the next day, so you won’t have to wait long at all, unlike some trades that take more time.

As with all planning in advance, you should set some money aside for contingencies. Sometimes builds go over budget thanks to last minute decisions and clients not understanding what’s included in the scope. The general recommendation is adding an extra 10 – 20% to the total budget.

Setting your plans in concrete

Planning a renovation or building project requires awareness, patience, and materials like concrete and rebar. You’ve met the interior designer to pick out paint colours and beento the furniture shop for a new couch. Getting the practical details right, though, is important.

 

(Tensile) strength

Concrete and rebar –  one won’t exist without the other in any commercial project. Rebar is laid and the wet mixture is poured over it. Because the bars have grooves, the concrete has  a strong ‘grip’ which prevents cracks.

Concrete is hardy and long-lasting, but only if the right type is used for the job. The slabs must withstand nature, traffic from people and machines, and anything else that will make it crack. Cracks in walls, ceilings, or support slabs spell disaster.

 

Have here or take away?

Cement mixes are readily available in hardware stores, and popular with DIYers. Professional concreters, though, will have ReadyMix cement trucks available. The barrel on the truck constantly turns, keeping the mixture at a good consistency and making sure the heavier stones don’t settle at the bottom.

Benefits of ReadyMix concrete include not having to make the mixture yourself. Amateur renovators might find this overwhelming and while it’s fun to watch the struggle on renovation shows, you might not laugh when it’s your turn. Another perk is knowing that  you’ve bought the right amount of cement. If you fall short, it’ll cost money that you delegated elsewhere on your budget.

 

DIY or a little extra help?

Unless you’re a builder or tradie who deals with concrete every day, it’s probably best to let the professionals handle the job. Experienced DIYers can order the premixed cement and do the work themselves to save money. The project, though, will go a lot faster with some experienced helping hands.

Professional concreters will come over in the early stages of the project for measurements. This way, you’re getting the right amount of concrete the first time. You don’t need to worry about running off to the hardware store for more supplies mid-project.
