River sand or machine sand, crushed stone sand, crushed gravel sand are the major sources of fine aggregate. Dolomite aggregates, crushed gravel or stone, natural disintegration of rock are the major sources of coarse aggregate. 5: Surface Area: The surface area of fine aggregates is higher.
The ratio of fine aggregate to coarse aggregate to be used in concrete is 1:2, which means that for every 1 part of sand we have to take 2 part of gravel. Hence we have to divide the Total Aggregate into 3 parts and take 1 part as sand and 2 parts as coarse aggregate. Lets calculate weight of sand and gravel needed for M15 Grade concrete.
