the mining of concrete and raw materials

Are You Mining Minerals for Cement, or for 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. Cement manufacturers mine and process raw materials and put them through a chemical reaction process to create cement. They need to
