About the Book: Principles of Reinforced Concrete Design
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. Since
concrete is a brittle material and is strong in compression. It is weak in
tension, so steel is used inside concrete for strengthening and reinforcing the
tensile strength of concrete. The steel must have appropriate deformations to
provide strong bonds and interlocking of both materials. When completely
surrounded by the hardened concrete mass it forms an integral part of the
