Description
One of the widely accepted approaches to decarbonizing the cement sector is the partial replacement of clinker with supplementary cementitious materials (SCM), such as slag, limestone, fly ash. Previous studies have shown that slag helps to inhibit the conversion of calcium aluminate cement. Due to the problems with the availability and cost of slag, there is a need to investigate other possible SCMs and their application potential in CAC. Calcined clay with medium kaolin content available in the region was used in this study. The evaluation of the hydration and conversion process was monitored by analyzing the microstructure and compressive strength up to 56 days. The results show the influence of strätlingite hydrate formation on the conversion process of CAC.
