Wet sieve analysis of fresh concrete

Introduction The main objective of the fresh concrete analysis is the determination of the cement content in the mix. It is not possible to completely separate the cement from the aggregate in the wet sieve analysis. Aggregate fines pass through a fine sieve while the coarse cement grains remain together with the washed aggregate.
