The original weight of the aggregate sample = W1 g The weight of the aggregate sample retained = W2 g Weight sample passing 1.7mm IS sieve = W1 – W2 g. Abrasion Value Formula. Abrasion Value = (W1 – W2 ) / W1 X 100. Sample Calculation. Let the weight of the aggregate be W1 = 5000 gram. Weight of the aggregate sample retained W2 = 2100 gram

Grading of Aggregates: Their Significance, Types and Analysis
The fineness modulus is a numerical value derived from the results of the sieve analysis. It serves as a measure of the overall fineness or coarseness of the aggregates. The fineness modulus is calculated by adding the cumulative percentages of aggregate retained on each sieve and dividing the sum by 100.
