It is packaged in bags of 25 kg. The sand is used for testing of hydraulic cement strength conforming to ASTM C 109.

Grading is determined by EN 933-1. The average grading is as follows:
|Square Mesh Size in (mm)||Percent Passing Sieve (%)||Percent Passing Sieve (%)|
|0,600||97||96 to 100|
|0,425||69||65 to 75|
|0,300||26||20 to 30|
