process in grading of fine aggregate

If FM2-3.5, it is fine. If FM5-5.5, it is coarse. Significance of grading of aggregates. If the aggregates are of uniform size, there will form voids. Therefore, the grading of aggregate is done to lessen those voids by accommodating smaller size aggregates in those voids. Grading of aggregates gives uniformity in the specific weight of concrete.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.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. When grading of aggregate is done by sieve analysis.
