摘要
FIELD: chemistry.;SUBSTANCE: invention relates to method of manufacturing fast setting light-weight cementing composition with improved compressive strength for building products such as panels. Method of obtaining light-weight cementing mixture, which has improved compressive strength and resistance to water, includes mixing water, cementing reacting powder, alkali metal salt of citric acid as set accelerator and light-weight filling agent, where weight ratio of water to reacting powder constitutes approximately 0.17-0.35:1.0, reacting powder includes 75-100 wt % of sol dust, which contains at least 50 wt % of fly ash of class C and 0-25 wt % of hydraulic cement and/or gypsum, setting of cementing mixture being achieved within from 4 to 6 minutes of composition mixing without addition of set retarder. Invention also deals with composition for obtaining light-weight cement panel.;EFFECT: obtaining light-weight cementing mixture, which has improved compressive strength and stability.;10 cl, 9 dwg, 9 tbl
