Question

Fine sand is generally used for which of the following works?

(a) Masonry

(b) Concrete structures

(c) Plastering

(d) Grinding and polishing

I had been asked this question in exam.

My question comes from Source and Classification of Sand in section Materials for Construction of Basic Civil Engineering

Answer 1

The correct answer is (c) Plastering

For explanation I would say: Plastering is the act of applying a layer of plaster over a wall. It gives the wall a smooth and decorative appearance. Hence, for achieving the smoothness, fine grained sand is employed.
