As this post suggests, the Biggest Cement Companies in the USA produce Cement as a building product. Cement is mainly used as a binder in Concrete, which is a basic material for all types of construction, including housing, roads, schools, hospitals, dams, and ports, as well as for decorative applications (for patios, floors, staircases, driveways, pool decks) and items like tables, sculptures or bookcases.
Therefore, Cement, in short, can be defined as a finely milled mineral powder, usually grey in colour. The primary raw materials for cement production are limestone, clay, and marl.
Through the Biggest Cement Companies in the USA, America accounts for more than four per cent of the world’s global cement supply.
The USA is the third-largest producer of Cement in the world. The majority of the top cement producers in the US are multinational companies with origins in countries such as Mexico, Switzerland, and Ireland.
At least 30 states in the US have cement-producing facilities, and there are 96 integrated cement-producing plants plus eight grinding facilities.
According to data from the US Geological Survey, the US currently produces close to 100 million tons of Portland cement. Below are the 10 Major Cement Companies in the USA.
