Özet

In the geotechnical field, Portland cement is frequently used as a chemical soil stabilization material. Considering the energy spent in the production of Portland cement and the excess CO2 produced, it is vital to reduce cement consumption to increase economic and ecological sustainability. Researchers are investigating the use of alternative materials with lower CO2 emissions and production costs compared to Portland cement in soil stabilization applications. This article investigates the effects of cement containing nano CaCO3 and calcined clay on the stabilization of expansive soils. In this study, different cement mixtures were obtained by replacing limestone calcined clay cement (LC3) with nano CaCO3. These stabilizer mixtures were mixed with the expansive soil sample at 4%, 6%, and 8% ratios and 10 mixtures were obtained to be subjected to the experiments. To investigate the soil stabilization effects, the mixtures were subjected to Proctor tests after determining the Atterberg limits. It was determined that the plasticity index and maximum dry density increased, optimum moisture content decreased with the utilization of the stabilizer mixture containing calcined clay and nano CaCO3.
