Question

The maximum bulking of sand is likely to occur at a moisture content of

• A. $5\text{\%}$
• B. $8\text{\%}$
• C. $11\text{\%}$
• D. $14\text{\%}$

Answer 1

The correct option is A $5\text{\%}$

The increase in the volume of a given mass of fine aggregate caused by the presence of water is known as bulking of sand. The extent of bulking depends upon the percentage of moisture present in sand and its fineness, with ordinary sand bulking varying from $15-30$ percent. It increases with moisture content up to a certain point $\left(\right(5-6\text{\%}),5\%)$ reaches maximum.
