Portland-pozzolan cement with increased strength properties

The paper is devoted to the problem of increasing the strength of portland-pozzolan cement by multifunctional additives. Today multifactorial additives for commercial concretes, which differ from other additives by its multi-component composition, are on demand. In this new quality multicomponent synnyrit and its varieties, which are a new type of ultrapotassium aluminosilicate raw material for the ceramic and cement industry, can be quite competitive for receiving non-chlorine potassium fertilizers, alumina and potash.
