The slabs, using Artificial sand, are more leak proof than by river sand Now a days, in construction of roads, buildings, dams, canals, etc, cement concrete plays an important role Concrete is an artificial stone resulting from hardening of rationally chosen mixture of binding material, water and aggregate (Sand and crushed stone or gravel)
The constituents of concrete are coarse aggregate, fine aggregate, binding material and water Rapid increase in construction activities leads to acute shortage of conventional construction materials It is conventional that sand is being used as fine aggregate in concrete For the past two years, the
The effects of aggregate type, size, and content on the behavior of normal and high-strength concrete, and the relationships between compressive strength, flexural strength, and fracture energy are discussed The concrete mixtures incorporate either basalt or crushed limestone, aggregate sizes of 12 mm ('h in) or 19 mm (:Y in), and
