Water absorption of all aggregate

Question

Accepted Answer

Water absorption of aggregate is a crucial factor in determining the quality and durability of concrete.

Water absorption of aggregate is typically measured by soaking the aggregate in water for a specific period of time and then determining the weight difference before and after soaking.
Lower water absorption indicates higher quality aggregate as it means less water will be absorbed into the aggregate during concrete mixing.
High water absorption can lead to lower concrete strength and durability.
Different types of aggregates have different water absorption rates, for example, porous aggregates like limestone may have higher water absorption compared to dense aggregates like granite.
