Sieve dewaxed and sieve analysis

£40 per sample

Synthetic surfaces containing a wax-based coating are initially dewaxed (see wax separation) and the sieving process separates the sand grains into specific sizes and is known as the particle size difference (PSD) or particle distribution. The PSD of the sand will have initially been selected according to its specific purpose and will additionally depend upon the other materials included in the surface. Sieve analysis is a simple yet critical test.
