RCC STRUCTURES are nothing but reinforced concrete structures. RCC structure is composed of building components such as Footings, Columns, Beams, Slabs, Staircase etc.
These components are reinforced with steel that give stability to the structure.
STAIRCASE is one such important component in a RCC structure.
In a public building, the stairs must be from the main entrance itself and located centrally, to provide quick accessibility to the principal apartments.
All staircases should be adequately lighted and properly ventilated.
Standard mix used for stairs are 3 parts cement, 2 parts sand, 4 parts gravel and water. It is recommended to use a concrete vibrator while pouring the concrete to completely fill the gaps of the stairs and to avoid the honeycomb formation.
