    What is RCC & PCC?

    Plain cement concrete (PCC) is a hardened mass obtained from a mixture of cement, sand, gravel, and water in definite proportions. ... If steel is kept in the concrete then it is called Reinforced cement concrete (RCC).

    What is the full form of RCC in construction?

    The full form of RCC is Reinforced Cement Concrete. Cement concrete is strong in compressive strength but weak in tensile strength. To increase the tensile strength, mild steel bars are used in cement concrete thereby reinforcing it./span>

    How is RCC done?

    Its full name is reinforced cement concrete, or RCC. RCC is concrete that contains steel bars, called reinforcement bars, or rebars. ... To make reinforced concrete, one first makes a mould, called formwork, that will contain the liquid concrete and give it the form and shape we need.
