Are You Mining Minerals for Cement, or for Concrete?

Aug 01, 2017 Cement is the grey powdery stuff that when mixed with sand, rock, gravel and water forms concrete. The concrete is the final product used in buildings, roads, infrastructure, etc. You can think of cement as the “glue” that holds the sand and gravel and re-bar (reinforcement bar) together to make concrete.

Sand mining Wikipedia

Sand mining is the extraction of sand, mainly through an open pit (or sand pit) but sometimes mined from beaches and inland dunes or dredged from ocean and river beds. Sand is often used in manufacturing, for example as an abrasive or in concrete. It is also used on icy and snowy roads usually mixed with salt, to lower the melting point temperature, on the road surface. Sand can replace eroded coastline. Some uses require higher purity than others; for example sand used in concrete must be free of seashell fragments.

The Hidden Environmental Toll of Mining the World’s

Feb 05, 2019 The Hidden Environmental Toll of Mining the World’s Sand. By far the largest mining endeavor globally is digging up sand, mainly for the concrete that goes into buildings. But this little-noticed and largely unregulated activity has serious costs — damaging rivers, wreaking havoc on coastal ecosystems, and even wiping away entire islands.
