describing the properties of coarse aggregate

The Effect of Aggregate Properties on Concrete. Aggregate is classified as two different types, coarse and fine. Coarse aggregate is usually greater than 4.75 mm (retained on a No. 4 sieve), while fine aggregate is less than 4.75 mm (passing the No. 4 sieve). The compressive aggregate strength is an important factor in the selection of aggregate.

Aggregate Gradation Optimization - Literature Search

2019-12-6  For almost 100 years, efforts have been made to achieve desired concrete properties through adjustments in aggregate gradation. Initial efforts dealt with the concept of maximum density with the idea that a denser gradation would contain fewer voids to be filled with cement paste. Unfortunately, mixtures formulated with few voids tended to be ...
