Aggregate Absorption: 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 absorption is used for applying a correction factor for aggregates in dry condition and determining water demand of concrete in saturated surface dry condition.

Concrete Information, Definition The Concrete .

Concrete is made up of three basic components: water, aggregate (rock, sand, or gravel) and Portland cement. Cement, usually in powder form, acts as a binding agent when mixed with water and aggregates. This combination, or concrete mix, will be poured and harden into the durable material with which we are all familiar.
