What Are The Parts Of Concrete

2022-09-18

Concrete is made of cement as a cementitious material, sand and stone as aggregates; it is mixed with water (which may contain admixtures and admixtures) in a certain proportion and is obtained by stirring.

The earliest concrete has no steel bars in it. This kind of concrete is called plain concrete.

Plain concrete is very brittle, so such concrete can only be used for structures that mainly bear pressure such as foundations and columns of houses, but cannot be used for structures such as beams and floors of houses that mainly bear tension.

The first revolution in concrete science was the addition of steel bars to plain concrete, which tightly wrapped the steel bars together. Such concrete is called reinforced concrete. When reinforced concrete is subjected to external loads, the two materials exert their respective mechanical characteristics: plain concrete is mainly used to bear pressure, and steel bars are mainly used to bear tension.
