Properties of steel can be predicted with a high degree of certainty. Steel in fact shows elastic behavior up to a relatively high and usually well-defined stress level. In contrast to reinforced concrete, steel properties do not change considerably with time. Speed of erection.
Steel Reinforcement Bars and its Important Characteristics
Jul 05, 2014· Reinforcement concrete (RC) is a composite material made up of concrete and some form of reinforcement most commonly steel rods, bars, wires or mesh of steel rods and steel wires. The steel reinforcement bars usually consists of such shape and size that they may easily be bent and placed in the concrete so as to form a monolithic structure.Steel Structures Vs Concrete Structures Complete,Mar 19, 2017· RC Beam Column Building. Concrete structure can be made with many different ways. Some are given below: Plain Cement Concrete. Plain cement concrete is a hardened mass obtained from a mixture of cement, sand, gravel, and water in definite proportion.
