Water Absorption of Aggregate - CivilWeb Spreadsheets

The water absorption value for aggregates describes the percentage increase in weight between the dry aggregate and the saturated aggregate. 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

Effect of water absorption by the aggregate on

When prewetted aggregate was used, this effect was eliminated. The water absorption by the lightweight aggregate also affected the early com­ pressive strength of concrete.
