RCC CONSTRUCTION
RCC buildings have become the most common trend in the building industry in India because of its durability, strength, low cost and many other attractive features. A combination of concrete and steel reinforcement that are cast into one piece and that work as a monolithic element can be referred as Reinforced Concrete. Both concrete and reinforcement are combined to form the building block of construction because of their properties that compliment each other. Concrete is weak in tension and strong in compression whereas steel is weak in compression and strong in tension, because of these alternate properties Reinforced Concrete can resist both tensile and compressive stresses acting on the structure. Steel has very high ultimate tensile strength that assists the structure to bear the tensile stresses.
The combination of concrete and steel is very effective because as the concrete hardens on curing, it adheres firmly to the steel rods and protects it from corrosion, the hydration of cement causes an alkaline medium. The reason for their monolithic behaviour is also due to the fact that both of them have approximately the same coefficient of linear expansions. Also the physical and mechanical properties of both these materials do not get affected during temperature variations within a range of -40℃ to 60℃ that makes it possible to use in almost all climatic regions.
