A Geochemical Model for Analyzing the Mechanism of Stabilized Soil Incorporating Natural Pozzolan, Cement and Lime
Abstract In this study, a geochemical model is proposed to analyze of strength increase mechanism of stabilized soils incorporating natural pozzolan, cement and lime. Modelling considered kinetics and thermodynamics of mineralogical transformations. The pozzolanic reaction between lime, cement, natural pozzolan and soil is successfully simulated by the geochemical model. The model shows that the quantity of C-S-H and C-A-S-H precipitation are suitable for the strength development of stabilized soils. The compressive and tensile strength are depended on the stabilized soils mixing ratios for soil, natural pozzolan, cement and lime. The good agreement between the numerical and experimental results for optimal mixing ratio shows that the geochemical model could be considered as a tool to assess the optimal mixing ratio, optimal content of natural pozzolan is $$15\%$$ . Moreover, the obtained results demonstrate that the soil of Dak Nong province in Central Highlands of Vietnam is inert in the process of soil stabilization, the natural pozzolan and lime are necessary to increase the amount of C-S-H as well as the strength.
