Grading of aggregate. Grading of aggregate is the particle size distribution, which is determined by sieve analysis. The particle size distribution of a mass should be such that, voids between the coarse aggregate should be filled by fine aggregates. The grading of the aggregate affects the workability of concrete.
To describe an aggregate by its maximum and minimum size is not sufficient. It has to be graded from its minimum to maximum size. IS383 recommends the following grading limit for fine aggregates.

Importance of aggregate grading. Ideally coarse and fine aggregate should be graded in such a way as to minimise the voidage. After compaction the volume of the cement paste must be more than the voidage between particles. Underfilling will result in entrapped air and an unworkable mix.
Grading of aggregates is aimed at determining the mean size of the particle in a given batch of aggregates. This is commonly found by the Method of Fineness Modulus. The method can be used to determine fineness modulus of coarse aggregates, fine aggregates, and allin aggregates, i.e., mixed aggregates.

The grading of the fine aggregate was then as BS 8821973 which defined the grading for four zones of fine aggregate as shown in Table 19.5. Although BS 8821973 has now been revised, Tables 19.319.5 are still of practical use as a guide to determining the ratio of fine to coarse aggregate required to make a dense mix.
When I asked my merchant if the sand he had given me was BS882 grade M he looked a bit blank. However I am a little worried that I may have a different type of sand soft and am very confused as to the different types and all the different names that they are given.
