Selection of concrete formulations for the creation of soil-cement piles in difficult engineering and geological conditions

Strengthening of soils by jet technology in difficult ground conditions has now become widespread, including in the construction of buried and underground structures. At the same time, a sufficient amount of experimental data has accumulated to predict the properties of the resulting soil cement. The purpose of the work is to determine the optimal consumption of materials for soil-cement structures, taking into account complex engineering and geological conditions.
The study of mineral-based hardening systems in water-saturated soils with inclusions of organic deposits or in conditions of high filtration has a number of features that make it difficult to assign optimal technologies and components of cement-based solutions for the formation of soil cements. To determine the final parameters of soil cement, the parameters of soil cement piles at the facilities during the construction of the subway, laboratory data on mixing mineral components and soils of different types, scientific and technical data were analyzed.
