Question

state the purpose of finding bulking of sand​

Answer 1

Explanation:

Why sand? The main purpose of adding sand in concrete is to minimise the segregation of concrete and to fill out the pores between the cement and coarse aggregate. This test (bulking of sand or bulking of fine aggregate) is to ensure that we are using the right amount of sand while concreting

Answer 2

Answer:

ANSWER.

Explanation:

BULKING in Sand.

This layer generates the force which makes particles to move aside to each other. This results in the increase of the volume of sand. Excessive presence of moisture content in the sand makes concrete to less durable and lose its strength.
