Sieve is tool that used to examine the size of a sample particle. Based on these examinations, the grain size distribution can be identified.

The objectives of the grain size examination are include :

− To get the size of the particle distribution in percent which is a calculation of the weight of the sample that being tested.

− To get the overall particle size distribution shown by a graph/distribution table.

− To determine the particle size classification

The particle size examination procedures using this sieve are include coarse and fine aggregates
