Water absorption limits on aggregates

Water absorption limits on aggregates. Limits on aggregate water absorption are rare though they may be useful to link to an undesirable concrete property, such as freeze-thaw susceptibility, as water absorption is easily determined. Historically it is not known the source of the limits

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 ...

Jan 01, 1996  Jan 01, 1996  The water absorption for the two series of concrete is shown in Table 5 and Fig. 2. It can be seen in the table that the water absorption, for both series, increases as the W/C ratio increases. The maximum absorption was observed at W/C ratio of 0.55. As the W/C ratio becomes larger than 0.55, water absorption decreases.

Aggregates for Concrete

Aggregates may be broadly classi fied as natural or artificial, both with respect to source and to method of preparation. Natural sands and gravels are the product of weathering and the action of wind or water, while manufactured crushed fine aggregate and crushed stone coarse and fine aggregate are produced by crushing natural stone.
