ABSTRACT:
A water-based mixture of multi compounds was invented for the purposes of treating and providing an ultimate protection for large areas of concrete pavements against moisture and moisture-associated problems. The mixture preferably works from within the concrete as well as at the surface. A water-repelling function prevents water from penetrating the concrete matrix. A hygroscopic and hydrophilic behavior of its crystallization system within a concrete matrix minimizes moisture transmission through capillaries and connected voids. As a result, the mixture promises to provide a permanent treatment for moisture related problems, such as damage caused by repeated freeze and thaw cycles and chloride ion penetration as from deicing salts, as well as a permanent treatment for the so-called alkali-silica reactions.
