Moving Toward a More Eco-Friendly Cement | …

They began by combining recyclable materials—mostly industrial waste—with lower amounts of limestone. Then they added a small amount of alkali chemical to the modified mixture, using a process that requires very little heat. Their estimate is that this alkali-activated cement emits 97% less CO 2 than traditional Portland cement. MIT Research: Scientists at the Massachusetts Institute of ...

The Environmental Impacts of Concrete - …

• Production of one tonne of cement results in 780 kg of CO2 • Of the total CO 2 output, 30% derives from the use of energy and 70% results from decarbonation • Important to realise is that although 5% of the worldwide generation of CO 2 is due to cement production, that level of output also reflects the unique and universal importance of concrete throughout the construction industry.

Why LC3? - LC3 - Limestone Calcined Clay …

Process emissions: as the limestone is heated, it changes into lime and CO 2. These emissions represent 60 to 65% of total emissions linked to cement production. Reducing the amount of clinker in cement, reduces the amount of CO 2 in the atmosphere. Now, the amount of clinker is reduced by half in LC3. LC3 allows growth without abstinence due to resources and CO2 efficiency . With current ...
