Websize of the aggregate and the particle-size distribution. 2. Recommended sample mass for each aggregate size of processed aggregates (such as sized aggregates for PCC and AC) or composite aggregates (such as AB and CTB) that are comprised of approximately 40 % or more of aggregate retained on the No. 4 sieve, are listed in Table 1. TABLE 1 Maximum WebOne of the physical properties of aggregate that influence the property of concrete is the grading of aggregate. The grading of aggregate defines the proportions of particles of different size in the aggregate. The grading of fine (size <5mm) and coarse (size >5mm) aggregates are generally required to be within the limits specified in BS 882: 1992.

Coarse aggregate has most of the product rationed on a No. 4 sieve and fine aggreate, like sand, passes a No. 4 sieve. This arbitrary line explains our having coarse-aggregate and fine-aggreate tables for gradation.
