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.

In order to measure the influence of UCW as a partial replacement of natural coarse aggregates (NCA) and natural fine aggregates (NFA) on the properties of concrete, mixtures are cast in two groups. In the first group, NCA are substituted with untreated coal coarse aggregates (UCCA) at seven replacement contents: 0%, 5%, 10%, 15%, 20%, 25% and ...
Grading Limit for Coarse-Grained and Fine-Grained Aggregates 4.1. Coarse-Grained Aggregates. The use of single-sized aggregates in concrete results in more voids, but it provides excellent resistance against sudden impact. On the other hand, graded aggregates contain different particle sizes of coarse aggregate, reducing the voids in concrete ...
