Impact of Waterproofing Permeable Capillary Mixtures on Cement Stone

The influence of a waterproofing penetrative capillary mixture on the composition and structure of cement stone was considered. It was shown that the change in the cement stone structure under the influence of a waterproofing permeable capillary mixture is accounted for by the interaction in general of the СO32− and HCO3− and HCOOal by t2+ and SO42− SOtHCOOal for the cement hydration products, that is, hydroaluminate of calcium and portlandite, to form the corresponding AFt and AFm phases as well as calcite. Calcium hydrosilicate needles play the most important role in the formation of the waterproof cement stone structure.
