Aggregates for Concrete
aggregate and crushed stone coarse and fine aggregate are produced by crushing natural stone. Crushing, screening, and washing may be used to process aggregates from either sand and gravel deposits or stone quarries. Aggregates may be produced from igneous, sedimentary, or metamorphic rocks, but geological type does not by itself make an …

Coarse Sand
With lower silt and clay contents, river sand improves the quality control of the concrete/mortar production because the presence of too much silt and/or clay would adversely affect the workability and strength of the concrete/mortar produced. Coarse river sand is recommended for reinforcement cement concrete (RCC) and brick / blockwork.
