Abstract
This paper examines an approach to reducing clinker content in cement systems through the use of carbonate low water-demand system. The selection of calcium-based carbonate systems is justified in comparison with magnesia-based binders, which are limited by high water demand and technological constraints. Based on an analysis, the carbonate low water-demand cement CNV-50KB is selected and compared with conventional Portland cement PC500D0. The comparison focuses on key technological parameters, including strength development at different curing stages and setting times. The results show that CNV-50KB provides mechanical and technological performance comparable to Portland cement while exhibiting reduced water demand and a lower clinker content. An environmental assessment based on published data indicates a reduction in specific CO2 emissions and production energy intensity. The findings confirm the potential of carbonate low water-demand cements as an effective and environmentally sound alternative to traditional Portland cement.
