Reinforced concrete is a composite material that combines concrete with reinforcement, typically in the form of steel bars (rebar) or mesh. The primary purpose of adding reinforcement is to improve the tensile strength of concrete, which is strong in compression but weak in tension. This combination allows reinforced concrete to withstand various types of loads and stresses more effectively than plain concrete.
Prestressed concrete construction is a technique used to enhance the strength and performance of concrete structures. This method involves the application of a pre-compression force to the concrete before it is subjected to external loads. The primary goal of prestressing is to counteract tensile stresses that occur when loads are applied, thus improving the structural performance and durability of the concrete.
