Changes in the structure of the cement rock in treatment with a penetrating waterproofing capillary compound.

It is demonstrated that, after treatment of the cement stone with penetrating waterproofing capillary compound (PWCC), a change in its structure takes place due to the interaction of the ions SO3 2-, HCO3 - and others with Portland cement hydration products to form AFt- and AFm-phases in the pore space. As a result, the cement stone compacts.
