• 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 toSand and Gravel Mining Industry Additional Information,Sand and Gravel Mining Process Once an aggregate deposit is found, the first step in extracting the sand and gravel is to clear the surface of vegetation and topsoil and dig a pit. Since the water table is so close to the surface in Nebraska, the pit fills with water and forms a lake.
