Game-Changing Concrete Technology | Carbicrete

Lower your carbon footprint through carbon-negative concrete. Carbicrete's process avoids the GHG emissions associated with cement production (about 2kg of CO2 per standard-size concrete block) and then injects CO2 (1kg per block) into its products. Because more CO2 is consumed than emitted during the process, it is carbon-negative, allowing users of the technology to lower their carbon ...

Cement - Wikipedia

This cement is made by heating limestone (calcium carbonate) with other materials (such as clay) to 1,450 °C (2,640 °F) in a kiln, in a process known as calcination that liberates a molecule of carbon dioxide from the calcium carbonate to form calcium oxide, or quicklime, which then chemically combines with the other materials in the mix to form calcium silicates and other cementitious compounds.

Concrete's strength is influenced by its moisture level during the hardening process: as the cement solidifies, the concrete shrinks. If site constraints prevent the concrete from contracting, tensile stresses will develop, weakening the concrete. To minimize this problem, concrete must be kept damp during the several days it requires to set and harden.
