Manufactured and crushed sands will usually have lower SE values than clean natural sands due to the dust of fracture created during the crushing process. Particle density and water absorption, which are functions of the mineralogical composition of the aggregate, were determined according to BS EN 1097-6:2000.

The effective absorption is used to calculate the weight of water absorbed (W abs) by the weight of aggregate (W agg) in the mix: W abs = (EA) W agg. If the aggregate is close to the OD condition when batched, it takes the aggregate some time to absorb all the water necessary to reach the SSD condition. Surface Moisture:

Therefore the absorption value is the amount of water which the aggregates are able to hold. The absorption value can be ascertained using the water absorption test described in BS EN 1097-6 and should generally be less than 2% in order to prevent large variations of water in the concrete mix during production.
