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.

How to Decide Which Concrete is Right for Your Home

Building or renovating your home is one of the most personal experiences. While many factors are involved, choosing the right concrete is often overlooked. If you are looking for concrete delivery in Brisbane, you might want to think again about choosing the right concrete.

Things to Check before Contacting Concrete Delivery Brisbane

Concrete might look like a single product, but it is a combination of many and depends on many properties. Depending on your needs, you need to check all of them:

Strength:

The primary criteria while choosing concrete should be the strength, or more precisely, compressive strength. It is measured as Pounds per Square Inch. 2500 PSI is generally suitable for driveways, floors etc. and used commonly in mini concrete Brisbane supplies. The more impact and extreme conditions it will the face, the higher the strength of the concrete should be.

Mixes:

The way concrete would be mixed also has its own importance. While going for concrete delivery Brisbane, it is important to know the type of mixes; whether it is pump mix, exposed aggregate mix, entrained air mix or flexible concrete.

Slump:

One of the most important concrete properties is a slump. It denotes the plasticity of the material and how easy it will be to use. Generally, a slump is increased by adding water.

Colour:

Though it might seem that grey is the only way concrete exists, it’s not quite true. By adding certain additives, you can get a variety of desired colours. This lowers the concrete prices Brisbane offers, compared to painting later on.

Finishing:

Once the concrete is dried and set, finishing is required to deem it ready for use. Floating and troweling are the most common finishing techniques, along with broom and salt finishing. Before concrete delivery Brisbane would ask for your expectations regarding the finished product.

Choosing the right concrete might look complex, but it is extremely necessary. Before you go for concrete delivery Brisbane, be sure to get all your queries answered.
