Reducing Environmental Impacts of Cement and Concrete

Portland Cement ManufacturingKiln OperationEnergy ConsumptionCarbon EmissionsConcrete is typically made up of 41% crushed rock, 26% sand, 16% water, 11% portland cement, and 6% entrained air. When combined, the cement and water form a slurry that flows between the aggregate and cures through a “hydration” process into a solid, rock-like mass. Portland cement, the key ingredient, was patented in 1824 by British bricklayer Joseph Aspdin and now accounts for about 95% of the cement market.
