The Environmental Impact of Concrete/ Cement Sawcutting

Feb 26, 2020 Cement is made throughout the world by heating limestone and clay to a high temperature in kilns, a process which releases high amounts of carbon dioxide. The fossil fuel generally used to heat these kilns also releases the gas as it burns. But modern society can’t do without cement.”

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. It is made from See more on buildinggreenAuthor: Brent Ehrlich
