Glass CompositionsOct 20, 2019· 74 units sand / units silica per unit sand = 74 units sand needed By convention, these masses of raw material are then normalized around an English ton of sand. Thus, for each mass of raw material needed, divide by 74 (the quantity of sand needed for the desired batch) and multiply by 2000 (pounds of sand around which the rest of the raw materials are normalized).
Sand Extraction: 1. Introduction GreenFactsIntroduction. 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 billion to billion tonnes a year for 2012 alone.
