Abstract

The article presents research on the development of effective dry building mixes with modifying additives based on domestic raw materials. The prospects of using local raw materials such as Ust-Kamenogorsk Portland cement, Novoalekseevsky sand (Almaty region), neutralized electrothermophosphoric slag of domestic production, wollastonite (Akmola region field) are shown. Wollastonite acted as a reinforcing ingredient that enhances the crack resistance of cement stone molded products. At the same time, the experiments carried out confirmed that hardening accelerators have a positive effect on the structure of cement stone at all levels: they increase the volume of micropores and reduce the volume of macropores with a slight change in total porosity. Studies have shown that the use of modifying additives from domestic raw materials can improve the technological properties of mixtures, namely, adhesion to mineral bases, high wear resistance and abrasion resistance, low shrinkage and sufficient elasticity.
