The Full form of RCC is Reinforced Cement Concrete. RCC is a process when plain cement concrete which is a mixture of cement, coarse aggregate and fine aggregate is reinforced with steel bars. It is generally a concrete that contains steel bars, which is also known as rebars or reinforcement bars. This combination of RCC works very well, as concrete is very strong in compression and steel is very strong in tension. It is easy to produce at site and also inexpensive.

An RCC building means the main structural members of the building, viz, beams, slabs, foundations, and columns are made up of RCC (Reinforced Cement Concrete). There are various ratios of RCC, generally 1:1.5: 3 and 1:2:4 ratios are used in construction work. Where cement concrete ratio 1:1.5:3 is used; it means 1 part of cement, 1.5 parts of fine coarse/aggregate sand and 3 parts of coarse aggregate is mixed. RCC is basically used in structures to provide the tensile strength that the concrete is ineffective to handle.

It is used in storage structures like water tanks, dams, tunnels etc. It is also used to build heavy structures like towers, walls, bridges, or under water structures, sky scrapers and tall structures.
