The advantage of reinforced concrete is due to ___________(a) monolithic character(b) moulding in any desired shape(c) fire-resisting and durability(d) monolithic character, moulding any shape and fire-resistingThe question was asked in semester exam.This intriguing question comes from Structural Designing and Thumb Rules topic in section Valuation, Reports Technical and Design Data of Civil Engineering Drawing

Answer»

Correct OPTION is (d) monolithic character, moulding any shape and fire-resisting

The best explanation: REINFORCED concrete (RC) is a composite material in which concrete’s relatively low tensile strength and DUCTILITY are counteracted by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel reinforcing bars (rebar) and is usually embedded passively in the concrete before the concrete sets. Reinforcing schemes are generally designed to resist tensile stresses in particular regions of the concrete that might cause unacceptable cracking and/or structural FAILURE. Modern reinforced concrete can contain varied reinforcing materials made of steel, polymers or alternate composite material in conjunction with rebar or not. Reinforced concrete may also be permanently stressed (in TENSION), so as to improve the behaviour of the final structure under working loads.
