  • Portland Cement : A Brief History The Screed Scientist®

    Portland cement, arguably one of mankind’s most important manufactured materials, was invented and patented by Joseph Aspdin from Leeds in 1824 Aspdin produced cement by heating powdered limestone mixed with clay in a furnace, and grinding the resulting clinker to a powder He called the product “Portland CementManufacturing Of Portland Cement Raw materials are homogenized by crushing, grinding and blending so that approximately 80% of the raw material pass a No200 sieve Mixture is fed into kiln & burned in a dry state silica and alumina from the clay undergo a solid state chemical reactionWhat Is Cement?
