CO2 emission indicators

The article presents research results on the influence of technological parameters on the technical and environmental characteristics of low-carbon ready-mix concretes. The study examines the impact of aggregate gradation, cement content, lignosulfonate or polycarboxylate modifiers, and wet fly ash additives on concrete properties. The research demonstrates that clinker- and CO2-intensity indicators collectively determine the clinker efficiency of concrete.

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.
