The mining of sand, a non-renewable resource 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.

Concrete vs Cement: What's The Difference? Howden

1. Mining for raw materials. The raw materials, mainly limestone and clay, are extracted from their quarries by blasting or drilling using heavy mining machinery. The raw materials are moved after extraction and then transported to the crushers via dumpers. Crushers are capable of handling chunks of quarry rock as large as an oil drum. 2. Crushing
