Cement - Wikipedia

Joseph Aspdins' son William Aspdin had left his fathers company and in his cement manufacturing apparently accidentally produced calcium silicates in the 1840s, a middle step in the development of Portland cement. William Aspdin's innovation was counterintuitive for manufacturers of "artificial cements", because they.

co2 emissions from cement production - ipcc-nggip

Cement is an important construction ingredient produced in virtually all countries. Carbon dioxide (CO2) is a by- product of a chemical conversion process used in the production of clinker, a component of cement, in which line (CaCO3) is converted to lime (CaO). CO2 is also emitted during cement production by fossil.
