Answer / er. munesh natrrajan[m.d. of

The following methods are used to check the quality of sand.

1. Sand should not contain any appreciable amount of clay
balls and harmful impurities such as alkalis, salts, coal,
decayed vegetation etc. The silt contents should not exceed 4%.

2. To check the quality of fine aggregates or sand; put
some quantity of sand in a glass of water. Then it is
vigorously shaken and allowed to settle. If the clay is
present in sand, its distinct layer is formed at the top of
sand.

3. To detect the presence of organic impurities in sand, a
solution of sodium hydroxide or caustic soda is added to
sand and stirred. If the color of solution changes into
brown, it shows presence of impurities.
