Determination of Water Absorption of Aggregates
Water absorption of aggregates is important factor in concrete.
It affects the workability, strength and durability of concrete.
It is important to check the water absorption of aggregates at frequent intervals and making changes in the concrete mix design accordingly.
IS 2386 part 3 states how to check the water absorption of aggregates used in concrete.

A wrongly calculated water absorption either increase the water cement ration or decrease it and affect the workability of concrete in initial stage.
If slump test not done regularly, the effect of wrongly calculated water absorption can be seen on the strength of concrete in later stage.

The format for recording of water absorption of aggregates is attached herewith.
