Abstract
The article investigated the compositions of road-building materials containing screenings of rock crushing, Portland cement, hydrolyzed lignin, modified by the stabilizing additive “Element”. The road-building compositions containing screenings of rock crushing, Portland cement, hydrolyzed lignin modified with the stabilizing additive "Element" were investigated. The optimal content of raw materials has been established, which allows to obtain soil-cements with a strength mark of at least M 60 - M 75. Using a model experiment, it was shown that the stabilizing additive “Element” is active and can interact with each of component of the raw materials. Using the methods of scanning electron microscopy, infrared spectroscopy, X-ray phase analysis, it has been experimentally shown that the processes of hydration, carbonization and increasing the connectivity of orthosilicate anions play a significant role in the structure formation of soil-cements.
