Importance of Concrete:
Concrete is the most important basic construction material because it is difficult to get another versatile and mouldable material like concrete at such a low cost. Concrete has following important characteristics:
(a) It has good compressive strength.
(b) It has good durability.
(c) It has required impermeability.
(d) It has good fire resistance.
(e) It has abrasion resistance.
Concrete is weak in tension. The weakness of concrete in tension can be overcome by providing reinforcement and pre-stressing techniques.
Following are the important projects in Civil Engineering where we use the concrete as a basic construction material.
(a) Roads,
(b) Bridges,
(c) Buildings,
(d) Railways,
(e) Airports,
(f) Dams, etc.
