This question was posed to me in my homework.

My enquiry is from Curing of Concrete in portion Cement Concrete Construction of Construction & Building Materials

Answer 1

The correct option is (a) Consolidation

The explanation is: The main aim of consolidation of concrete is to eliminate air Bubbles and thus to give maximum density to the concrete. The importance of consolidation of concrete can be seen from the fact that a presence of 5% of voids reduces 30% strength of concrete.
