Application of thermodynamic model to mix design of stabilized soils

Abstract

The purpose of finding suitable mixes for construction, sample experiments of each mix design of stabilized soils should be tested. However, in order to improve the accuracy of the experiment, the number of samples to be conducted is high, leading to high accuracy of the test results. The basic mechanisms are general so they have not really analyzed in detail the reclamation mechanism of basalt soil. The unspecified mineral mechanism will participate in the soil stabilization process. Based on the thermodynamic model, the paper focuses on explaining in detail the role of each mineral component of the soil for improving the mechanical properties of stabilized in soil. As well as the reaction mechanism of the binder mixture with the mineral components of the soil. The results of the model are compared relative to the experimental results to determine the correctness of the thermodynamic model as well as the results of the experiment, proving the feasibility of reinforcing basalt soil by mixture natural pozzolan, fly ash and cement. Mineral content of different mix designsis predicted by thermodynamic model thereby predicting the mechanical capacity of each mix design.
