Sand Extraction: 1. 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.

Multiply these three values to get the volume in cubic feet, divide it by 27 to get cubic yards and finally, multiply your result by 1.5 to get how many tonnes you'll need.

The Density of Common Rocks and Minerals

Jan 23, 2020 · The densities of rocks and minerals are normally expressed as specific gravity, which is the density of the rock relative to the density of water. This isn't as complex as you may think because water's density is 1 gram per cubic centimeter or 1 g/cm 3. Therefore, these numbers translate directly to g/cm 3, or tonnes per cubic meter (t/m 3).
