The influence of complex additives on the strength and durability of cement composites under environmental conditions is considered. The PFM-NLK additive of factory manufacture is a mixture of a superplasticizer with the addition of an air-entrapping and hydrophobic complex. The second complex additive contained a superplasticizer, sodium tetraborate and boric acid. The content of the superplasticizer is common for additives. It allows you to reduce the I /C of the mixture and thereby increase the density and strength of the composite, and accordingly its frost resistance and corrosion resistance. Hydrophobic and air-entrapping PFM-NLK complexes additionally contribute to the formation of a material structure with increased frost resistance. Boric acid and sodium tetraborate form a borate buffer system, which leads to a softening of the “chemical shock” and thereby further increase corrosion resistance. As a result of the conducted studies, the effectiveness of complex additives was revealed and the regularity was confirmed that if each factor individually contributes to the improvement of the property, then with their combined action the effect becomes greater. The components of PFM-NLC, when combined, contribute to obtaining a material structure with high frost resistance. An additive containing a hyperplasticizer, boric acid and sodium tetraborate leads to an increase in strength and acid resistance.
