obtained by mixing cement, sand, and aggregates with water. Fresh concrete can be moulded into almost any shape, giving it an inherent advantage over other materials.
 Steel reinforcement is available in the form of plain steel bars, deformed steel bars, cold-drawn wire, welded wire
fabric, and deformed welded wire fabric. In Sri Lanka Reinforcing steel must conform to applicable British/ European standard specifications.
