Reinforced Cement Concrete Structures

Theory of R.C.C.

Concrete is reasonably strong in compression and weak in tension, where steel is good in tension and the combination of these materials makes an ideal and popular material known as reinforced cement concrete. Generally, steel rods used resist tensile forces, but in some cases they are also used to resist a part of the compressive force either because of natural constraints in construction or because of secondary requirement.

Merits of R.C.C

The coefficient of linear expansion of steel and concrete are almost same.

Concrete can be moulded to any shape and size and its ingredients are easily available.

It is economical in construction and its maintenance cost is practically nil.

It is durable and not easily affected by atmospheric agencies.

It is fire resistant and its construction is superior to steel and timber construction.

Monolithic construction in concrete is possible which provides greater flexibility in planning and design.
