Demand for and environmental impacts of sand mining ...

Sand is mined for many applications, but the largest use by far is for fine aggregate in concrete. Smaller quantities of sand are used for fracking, water treatment (filtration), metal casting, and making glass, silicon chips, and ceramics. Concrete consists of cement, water, fine aggregate (sand), and coarse aggregate (gravel).

Construction aggregates are produced from naturally occurring mineral deposits, including solid rock formations such as limestone and granite, and from loose deposits of sand and gravel. The most common structural uses of construction aggregates include the coarse and fine mineral components in Portland cement concrete and asphalt.

EXPERIMENTAL STUDY ON EFFECT OF SILICA SAND AS …

Conventional concrete which is produced by the mixture of cement, coarse aggregates, fine aggregates, and water is less environmental friendly due to calcination and mining of sand in river and sea. Polymer concrete is thus promoted where the cement and fine aggregates are replaced partially within itself. In this study, mechanical properties such
