Question

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.

(a) True

(b) False

I had been asked this question in exam.

The origin of the question is Earthwork, Concrete and R.C.C. work in division Rules and Methods of Measurement of Civil Engineering Drawing

Answer 1

Correct choice is (a) True

The best explanation: 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.
