AbstractAbout AuthorsReferences
The basic demands of impregnating-bridging compositions to inhibit the alkali-silicate reactions and to prevent deformations of concrete and destruction of constructions are identified in the paper based on analysis of the impregnation kinetics of capillary-porous body. The results of studies of changes in properties of solution of lithium nitrate and lithium carbonate from them concentration, kind and amount of surface-active substance are presented. Assessment of efficiency of studied impregnating-bridging compositions was performed by calculation of complex parameter. Selection of the optimal content of the compositions was made. The most effective composition is Li2CO3 (c=1.25%) with 0.0001% nonionic surfactant ALM-7s.
