Concrete Mix Design: Understanding Aggregate NPCA
Results are expressed as mass per volume. For example, a given crushed limestone could weigh 93 lbs./ By knowing the DRUW of a coarse aggregate, the maximum nominal aggregate size and the fineness modulus of the fine aggregate, the weight of the coarse aggregate needed per cubic yard of concrete mix can be estimated.

Materials Rollercompacted concrete
The different gradation requirement comes from the need of the Roller Compacted Concrete aggregate skeleton to be consolidated under compaction efforts from the paver and the steel drum and rubbertire rollers. The fine and coarse aggregate gradation should be selected to ensure workability, compactability, and surface finish.

Concrete Mix Design Procedure and Example IS456
Concrete mix design is the process of finding the proportions of concrete mix in terms of ratios of cement, sand and coarse aggregates. For, a concrete mix of proportions 1:2:4 means that cement, fine and coarse aggregate are in the ratio 1:2:4 or the mix contains one part of cement, two parts of fine aggregate and four parts of coarse aggregate.
