Question

When sand is fully dry then it’s volume is ____________

(a) Equal

(b) Less

(c) More

(d) Can’t say

I got this question in semester exam.

This question is from Bulking of Aggregates in chapter Aggregates and Testing of Aggregates of Concrete Technology

Answer 1

The correct answer is:

(b) Less

When sand is fully dry, its volume is less compared to when it is moist or wet. This is because dry sand does not contain any water in the pores between the particles, unlike moist or wet sand, which has water filling the voids, causing the volume to increase. The bulking effect occurs when sand contains moisture, leading to an increase in volume.
