the mining of raw materials for concrete

Are You Mining Minerals for Cement, or for Concrete?

2017-8-1  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 ...

The Cement Manufacturing Process - Advancing Mining

2015-8-20  Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln. In this process, the chemical bonds of the raw materials are broken down and then they are ...

Sand Extraction: 1. Introduction - GreenFacts

2022-1-2  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.
