Lab Test
Standard(s): BS EN 933-1:2012
Particle Size Distribution

BS EN 933-1:2012 specifies the test method used to determine the particle size distribution (grading) of aggregates by dry or wet sieving. The procedure defines how to separate aggregate particles into size fractions and calculate the proportion retained on each sieve.

This data is essential for assessing compliance with specification limits and understanding material suitability for concrete, asphalt, and other construction applications.
