Explain the term concrete.
Concrete is a Heterogeneous mixture of cement, fine aggregates (sand) and coarse aggregates mixed with water which hardens with time. It is basically used as a construction material.
Concrete technology deals with the study of the properties of concrete and its practical applications.
Properties:
- Mechanical strength: Concrete has high mechanical strength.
- Durability: Concrete is well-suited for structures exposed to demanding and extreme conditions like frost, rain atmospheric pollution, etc.
- Porosity and density: The denser (or the less porous) the concrete the better its performance and the greater its durability.
Uses:
Concrete is used to make various structures like
- Construction of Dams
- Residential Buildings.
- Commercial Buildings.
- Roads
- Marine Construction.
- Sewers.
- Foundations, etc.
[Extra information: Heterogeneous mixture is a mixture containing two or more substances mixed together, non-uniformly. As in concrete, the individual components can be seen separately and they are not uniformly distributed throughout the mixture, hence they are known as a Heterogeneous mixture.]
