How concrete is made material manufacture making how Waste Materials Used in Concrete Manufacturing
When United States industry figured out how to make Portland cement during the early s the production of natural cement in America began to decline After the refinement of Portland cement the next major innovation in concrete technology occurred during the late nineteenth century when reinforced concrete was inventedThese waste materials can partly be used or processed to produce materials suitable as aggregates or fillers in concrete These can also be used as clinker raw materials or processed into cementing systems New grinding and mixing technology will make the use of these secondary materials simpler
