Concrete is the most popular building material around the world. Concrete is made of cement, water, and coarse aggregates. When mixed together, they create a construction material that hardens over time.
How much water and cement you use determines the properties of concrete, such as:
- Resistance to heat or radiation.
There are several different types of concrete, even though they look very similar. Here are the most common types:
- Reinforced concrete –
This is concrete in which metal bars or wire is embedded to increase its tensile strength.
In addition, it’s used for construction on a large scale. Such as bridges, dams, tall buildings, and stadiums. This concrete has the following properties:
High relative strength
Good bond to the concrete
High toleration of tensile strain
- Lightweight concrete
Lightweight concrete is a mixture made with lightweight coarse aggregates. Such as shale, clay, or slate, which gives it its characteristic low density. This concrete has an in-place density of 90 to 115 lb/ft3. This makes it ideal for building modern structures that require minimal cross-sections in the foundation.
- High-strength concrete
In addition, HSC is a strong, hard-wearing blend of cement and 10mm coarse aggregate. High-strength concrete can resist loads that normal-strength concrete cannot.
- Hight-performance concrete
A concrete mixture that has high workability, high strength, and high density. This has a lot of benefits such as,
Firstly, ease of placement
Long term mechanical properties
Early age strenght
Finally, life in severe environments
- Precast concrete (PC)
In addition, precast concrete is prepared, cast, and cured off-site. Usually in a controlled factory environment, using reusable moulds.
