After the concrete hardens the form work is removed.
Full form of rcc roof.
Forming for the roof begins with post or scaffold type shoring erected to support wood joists and stringers like those used in conventional sus pended slab construction.
Rcc full form in civil engineering is reinforced cement concrete.
Plain cement concrete is mixture of sand cement and aggregate and reinforced cement concrete rcc is mixture of sand cement and aggregate including steel.
These steel bars are plain in surface or round sections diameter from 6 to 50 mm.
And what is properties and uses of rcc in civil engineering.
A cage of reinforcements is prepared as per the design requirements kept in the form work and then green concrete is poured.
Concrete is good in resisting compression but is very weak in resisting tension.
And we know concrete is two types plain cement concrete and reinforced cement concrete rcc.
The full form of rcc is reinforced cement concrete.
Rcc is a combination of concrete and steel to build a structure instead of using only concrete.
Shuttering materials such as wooden ballies planks and iron plates etc.
Cement concrete is strong in compressive strength but weak in tensile strength.
Raw materials for rcc slab roof.
On the other hand steel has high tensile strength and the bond between steel and concrete is good.
To increase the tensile strength mild steel bars are used in cement concrete thereby reinforcing it.
