Abstract

The management of the rheological properties of the cement systems and the kinetics of solidification by the use of specially designed complex modifiers has been proved. Modification of cement systems was made possible by the use of a complex modifier (CM) obtained as a result of the interaction of the hyperplasticizer GLENIUM 313 with liquid glass. The peculiarity of this method lies in the gel removal of the mineral component contained in the modifier. This complex modifier is used in conjunction with water when cement systems are solidified. It has been established that the application of CM in 1.0% of cement mass allows to reduce the amount of cement dough by 1.5 times, extends the retention period, and increases the strength of the solid on the first day by 2 times compared to the unchanged systems.
