Wet sieve analysis of fresh concrete — Correction

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.

To obtain high strength concrete, coarse aggregate size is usually held to a maximum size of 19 mm, but additional cement is required for the additional surface area. The fine aggregate can generally contain less material passing 300 um and 150 um sieve because of the higher cement content.
