Concrete is a hardened building material created by combining a chemically inert mineral aggregate (usually sand, gravel, or crushed stone), a binder (natural or synthetic cement), chemical additives, and water. Although people commonly use the word "cement" as a synonym for concrete, the terms in fact denote different substances: cement, which encompasses a wide variety of fine-ground powders

Manufactured sands tend to be used in mixtures in areas where natural sand is not available or not cost effective to be hauled to the needed location. MFA tends to be more angular and flaky due to the crushing process. Highly angular particles tend to increase the paste content of concrete because additional lubrication is required for particles with sharp corners.

The use of manufactured sand makes sense from various perspectives. First, manufactured sand is more uniform in structure compared with natural sand. It also has an advantage when it comes to concrete production, because manufactured sand is less needed in the concrete mix by a margin of 5 to 20% compared with natural sand to fill the voids

Cement is manufactured by heating a precise mixture of finely ground limestone, clay and sand in a rotating kiln to temperatures reaching 1450ºC. This results in the production of cement clinker, an intermediate product in the manufacture of cement. The cement clinker emerges from the kiln, is cooled, and then finely ground to produce the powder we know as cement. The fuels combusted to heat

How Concrete is Made. In its simplest form, concrete is a mixture of paste and aggregates, or rocks. The paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.

In its appraisal, concrete produced from recycled sand and aggregates is unfairly pitted against higher-strength concrete produced using aggregate, such as granite or basalt, and natural sand. It is fair to say that not all granite or sandstone deposits display the same strength characteristics and therefore selective end-use logic is applied.
