  • Concrete Sand | Southern Crushed Concrete

    Concrete Sand from Southern Crushed Concrete is a fine aggregate that is used in the production of concrete or mortar. Concrete sand is crushed in a quarry then filtered to ensure no large rock fragments are left behind. When mixed with cement and water, a grout is formed that fills the voids between the coarse aggregate.

  • Sand Extraction: 1. Introduction - GreenFacts

    Introduction. Sand and gravel are used extensively in construction. In the preparation of concrete, for each tonne of cement, the building industry needs about six to seven times more tonnes of sand and gravel (USGS, 2013b). Thus, the world’s use of aggregates for concrete can be estimated at 25.9 billion to 29.6 billion tonnes a year for 2012 alone.
