Abstract
The work shows the efficiency of using the SСADC reagent as an additive in cement-polymer mixtures. It also outlines physicomechanical properties of the cement slurry and the stone formed on their basis at temperatures of 22 C and 80 C. The main regularities of the formation of structures of various levels in cement-polymer solutions are revealed, depending on the degree of filling and the type of introduced modifications of the SСADC reagent. It was found that an entangled fibrous structure is formed between the hydrated cement minerals and the complex additive SСADC. At a concentration of 0.2%, it provides a self-healing effect for a damaged cement stone, and also improves the properties of cement-polymer grouting mixtures, contributing to a decrease in the filtration rate of the solution to 30%, an increase in bending strength by 25-27% and by 36-42% in ultimate strength for compression.
