Structural member of rcc slabs beams columns foundation 34.
Rcc denotes re in forced cement concrete in which cement sand and bajri are laid with the help of mild steel.
Rcc roof slab in the construction industry when they use the word concrete they are talking about reinforced cement concrete also known as rcc.
Design the roof slab beam and column of house given in figure 1.
This is most important part of the structure generally 1 2 4 and 1 1 5.
The capability to carry loads by these materials is magnified and because of this rcc is used extensively in all construction.

The location of the construction joint shall be at the one third span.
Crack in the roofs over a period of time the rcc shrinks forming cracks in the roof.
Of 0 24 shall be used for the roof slabs since it is subjected to higher temperature.
