The ingredients to be tested: water, fine aggregate (sand), coarse aggregate, cement, chemicals, reinforcement, and soil. The values of the physical properties obtained after testing will be used as the basis for all concrete mix design considerations. This will ensure the structure will be sound and prevent failure of the mix.

Calculating Aggregate absorption. For any mix design, the coarse aggregate is considered to be in saturated surface dry condition. Where as, the metal on the site is often in bone-dry condition. (Especially during summers). This dry aggregate often absorbs the water added in concrete and reduces the workability of concrete.
