clinker factor

The article presents the results of studies of the influence of technological factors (clinker factor of cements, grain composition of aggregates, cement consumption in concrete, modifier additives) on technical and environmental indicators of concrete efficiency. It has been shown that in combination, the parameters of clinker and CO2 intensities characterize the clinker efficiency of concrete, which can be improved by replacing part of the clinker in mixed cements with active mineral additives.

There were analyzed the ways of reduction of СО2 emissions in the cement industry. It was shown that a significant reduction of СО2 emissions in construction is achieved through the using of composite cements with a lower clinker factor that meets the requirements of the low carbon strategy for the cement industry. In this case, the replacement of part of Portland cement clinker with mineral additives in such cements leads decreasing of their strength, especially at early age.
