How Coarse Aggregate Affects Mix Design of Concrete?
5. Aggregate Absorption. Aggregate absorption is used for applying a correction factor for aggregates in dry condition and determining water demand for concrete in saturated surface dry condition. Aggregate can absorb water up to 2 % by weight when in bone dry state. However, in some cases, the aggregate absorption can be as high as 5%.
