5 Different Types of Concrete Used in Construction

“First you get some gravel, Pour it in the vout
To mix a mess o’ mortar you add cement and water…” “Cement Mixer” by Slim Gaillard
At its core most cement is composed of sand, rock or gravel. However, don’t let these basic components fool you. Concrete has developed and has become both advanced and increasingly diverse as the uses for it vary depending on the requirements of the final project/structure. Details of the various types of concrete, their properties and applications are discussed below:
- Normal strength concrete: Normal concrete is made by mixing the basic ingredients of cement; water and aggregate. The strength of this type of concrete is sufficient for most, but not all, construction projects. Moreover, the strength of normal concrete varies between 10MPa to 40MPa and it sets within about 30 to 90 minutes.
- High-strength concrete: As we said, normal concrete is not suitable for all constructions projects. This concrete differs from normal-strength concrete in the amount of force it can resist without breaking. In fact, it has the compressive strength of over 6,000 psi (pounds square inch).
- High-performance concrete: High-performance concrete differs from high strength concrete in that it dries quicker and reaches the peak of its strength in a relatively shorter amount of time. High-performance concrete is often used in freeway construction. This means that it must be and is strong, easy to use and able to withstand a great degree of stress.
- Lightweight concrete: Believe it or not, concrete does not always have to be indestructible. For example, if the concrete used in a project is purely decorative and will not be supporting important structures then it does not need to be as strong as normal or high-performance concrete. Examples of such items made from lightweight concrete include courtyard walls or the curbing around a yard, etc.
- Polymer concrete: Polymer concrete’s primary ingredients include water, sand and gravel. Its main benefits are that it is very weather resistant and can set very quickly. Moreover, polymer concrete is safer and more durable than ordinary concrete and can be used in a variety of construction applications.
