 Fineness Modulus Of Fine Aggregate

classification of aggregates, sand | 3rd sem | lecture,fineness modulus of aggregate (sieve analysis) it is a numerical index, which gives a general idea about the coarseness ( mean size of aggregates) it doesn’t provide any information regarding particle size distribution in the sample of aggregates. it is calculated by using the formula as : fineness modulus = cumulative % retained on each sieve / 100.classification of aggregate - classification based on size,the fine aggregates can be classified as coarse, medium and fine sands based on the fineness modulus. fine sand - fineness modulus of 2.2 to 2.6. medium sand - fineness modulus of 2.67 to 2.9. coarse sand - fineness modulus of 2.91 to 3.2. according to particle size distribution, is: 383 -1970 has divided the fine aggregate in to 4 grading zones..
