06/08/2020  The use of structurally efficient sections such as rib or voided slabs also reduces the volume of concrete and hence the embodied carbon. Superplasticiser admixtures can also help reduce the embodied carbon by reducing the water/cement ratio. This provides a stronger concrete for the same quantity of cement.

Low Carbon Concrete - Zero Energy Project

09/11/2020  The Number One Source of Embodied Carbon in Buildings. The cement used in concrete is produced by burning limestone in kilns at very high heat (2,300° to 3,000° F) usually using powdered coal or natural gas as fuel, wasting a great deal of energy and releasing carbon dioxide (CO2) from the combustion. The chemical reaction involved in making cement releases more CO2 as a byproduct.
