Crushed gravel may look similar to crushed stone and fall into the same bracket of material, but the key difference between the two is that crushed gravel is not made by man. Crushed gravel comes in the same form that it’s found, there are no additives or other stones mixed in. And due to its organic nature, unlike crushed stone, you won’t find gravel having many ragged edges. It comes in

Cement consists of finely ground Portland cement clinker and calcium sulphate (natural gypsum, anhydrite or gypsum from flue gas desulphurisation). In addition, cement may contain other main constituents, such as granulated blastfurnace slag, natu-ral pozzolana (e.g. trass), fly ash, burnt oil shale or limestone.

Bricklayer Joseph Aspdin of Leeds, England first made portland cement early in the 19th century by burning powdered limestone and clay in his kitchen stove. With this crude method, he laid the foundation for an industry that annually processes literally mountains of limestone, clay, cement rock, and other materials into a powder so fine it will pass through a sieve capable of holding water.

Hence the crushed sand will have greater water demand than that of natural sand resulting in slightly higher cement consumption. However, if crushed sand is properly graded with adequate fines the mix may have lower water demand when compared to poorly graded natural sand. Besides crushed sand can afford better control on gradation when compared to natural sand. Hence crushed sand may become

Limestone may appear in crushed concrete as a material found in the cement used to mix concrete. Some builders use crushed concrete as a material for new concrete, in which it takes the place of a crushed mixing stone like limestone. Crushed limestone appears in some of the same applications as crushed concrete. How Far Will 8 tons gravel cover?
