Reinforced Concrete Design

Concrete Concrete is a stone like substance obtained by permitting a carefully proportioned mixture of cement, sand and gravel or other aggregate and water to harden in forms of the shape and of dimensions of the desired structure Reinforced cement concrete Since concrete is a brittle material and is strong in compression It is weak in tension, so steel is used inside concrete for ....
