Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete. After harvesting, aggregate is processed crushed, screened, and washed to obtain proper cleanliness and gradation.

The aggregate sample is sieved through a set of sieves and weights retained on each sieve in percentage terms are summed up. On dividing this sum by 100, The Fineness Modulus of that aggregate is determined. This helps in deciding about the quantity of aggregates of known fineness moduli to be mixed for obtaining a concrete of desired density.

Raw Materials. Salt is obtained from two sources rock salt and brine. Rock salt is simply crystallized salt, also known as halite. It is the result of the evaporation of ancient oceans millions of years ago. Large deposits of rock salt are found in the United States, Canada, Germany, eastern Europe, and China.
