Question

Wet cement can cause severe skin burns if not washed off with water immediately.

(a) True

(b) False

This question was addressed to me during an online exam.

My question is taken from Properties of Cement in section Materials for Construction of Basic Civil Engineering

Answer 1

Right answer is (a) True

To explain: Cement is highly alkaline and setting process is exothermic.  Wet cement is strongly caustic and causes skin burns.  Similarly, dry cement causes eye or respiratory irritation, when it comes in contact with mucous membranes.
