14.4.2017· 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.

Get PriceClassification of Aggregates Aggregate is usually described as either coarse aggregate (retained 4.75 mm) or fine aggregate (passing 4.75 mm). Aggregates generally make up about 95 percent of the total mass of hot-mix asphalt mixtures and 80 percent by mass of concrete - aggregate properties are, therefore, critical for quality hot-mix asphalt or concrete.
