PROPERTIES OF CONCRETE
1. Concrete is very strong in compression. In reinforced
concrete the compression is taken by concrete and tension by steel.
2. Concrete is very durable under normal conditions of
exposure.
3. Concrete can be moulded into any form. It can be poured
into any mould of any size and shape, when it is fresh and it takes the shape
of the mould after it sets and hardens.
4. The Coefficient of expansion of concrete match with that
steel. Even though the coefficient of expansion of concrete depends on the
aggregates used, its value with the common types of aggregates is around 10x10-6
to 14x10-6 per degree centigrade and that of steel 13x10-6
per degree centigrade. This is one
of the reason that concrete and steel match well and reinforced concrete is
durable with temperature changes.
5. Good impermeable concrete protects steel from corrosion.
6. Concrete is economical as compared to other manufacturing
materials like steel is low in cost.
7. Concrete can be made of the material available locally.
8. Concrete can be manufactured to special requirements.
Specials Concrete like strength, self compacting concrete, air entraining
concrete, light weight concrete, coloured concrete, pumpable concrete etc. can
easily made by adding certain chemical to concrete.
9. As concrete is heavy in weight, It is the ideal material
for gravity structures like dams and retaining walls.
