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%.

Aggregate is usually described as either coarse aggregate (retained 4.75 mm) or fine aggregate (passing 4.75 mm). Aggregates generally make up about 95 percent of the total mass of hot-mix asphalt mixtures and 80 percent by mass of concrete - aggregate properties are, therefore, critical for quality hot-mix asphalt or concrete.
