24/02/2017  Grading of Aggregates. Grading of Aggregates is one which is made up of stones of different sizes, ranging from large to small (inclusive of sand) so as to have minimum of air voids (and that will have maximum density) when mixed together. In grading of aggregates, the voids in the mixed aggregate would be minimum when the sand is just sufficient to fill the voids in the coarse aggregate. Voids in the coarse aggregate

Grading of aggregates Types of aggregate Significance

Grading of aggregates gives uniformity in the specific weight of concrete. Grading of aggregates reduces the chances of segregation in concrete. The graduation curve is also used to estimate the type of soil. The graduation curve is used to calculate the coefficient of uniformity and coefficient of curvature. It helps to determine parameters like D30, D60, and D10 which can be used as design

The grading of fine aggregate has a significant effect on the workability of the concrete mix. The Fineness Modulus is used in US practice and is a measure of the grading of fine aggregates. It can be calculated from a sieve analysis by adding the cumulative percentages of fine aggregates retained on the following sieve sizes; 0.15mm, 0.30mm, 0.60mm, 1.18mm, 2.36mm and 4.75m.
