Are You Mining Minerals for Cement, or for Concrete?

2017-8-1  Limestone is one of the key minerals used in cement making. Limestone is a sedimentary rock composed mostly of the calcium carbonate (CaCO 3) and, according to the Mineral Education Coalition, comprises about 15% of the Earth’s sedimentary crust. Surface mining is the general excavation method. There are a few underground limestone mines, but ...
