One reason why the carbon emissions are so high is because cement has to be heated to very high temperatures in order for clinker to form. A major culprit of this is alite (Ca 3 SiO 5), a mineral in concrete that cures within hours of pouring and is therefore responsible for much of its initial strength. However, alite also has to be heated to ...
By using this form of concrete, companies can reduce their emissions by 3% to 5%. CarbonCure estimates it has saved around 450,000 metric tons of CO 2 to date. Read More: How Cities Are Clamping ...
Limestone Calcined Clay Cement is a low-carbon alternative to the standard Portland cement. [33] [15] LC3 can reduce CO 2 emissions related to cement manufacturing by reducing the amount of clinker, replacing it with finely ground limestone and calcined clays.
As the main energy-consuming and greenhouse-gas–emitting stage of cement manufacture, improvement of kiln efficiency has been the central concern of cement manufacturing technology. Emissions from cement kilns are a major source of greenhouse gas emissions, accounting for around 2.5% of non-natural carbon emissions worldwide. [1]
