Masonry materials that resist efflorescence and are colored with increased intensity and permanence and methods of producing such materials
Abstract
Abstract EFFLORESCENCE OF MASONRY STRUCTURES COMPOSED OF COLDHARDENED MASONRY MATERIALS, SUCH AS, CONCRETE, SANDLIME BRICKS, ASBESTOS CEMENT AND CEMENT PLASTERWORK, OR OF STONE OR FIRED BRICKS, IS SUPPRESSED BY THE CONDENSATION PRODUCT OF AT LEAST ONE ALKYLENE POLYAMNE AND/OR POLYALKYLENE POLYAMINE, AND EPICHLORHYDRIN. THE CONDENSATION PRODUCT IN THE FORM OF AN AQUEOUS OR MORE VOLATILE SOLUTION THEREOF MAY BE APPLIED TO THE SURFACES OF THE MASONRY STRUCTURE OR, IN THE CASE OF SUCH STRUCTURES COMPOSED OF COLD-HARDENED MATERIALS, IS PREFERABLY INCORPORATED IN SUCH MATERIAL PRIOR TO THE HARDENING OR SETTING THEREOF. THE CONDENSATION PRODUCT IS FURTHER FOUND TO INCREASE THE COLORING POWER AND PERMANENCE OF PIGMENTS WHEN ADDED WITH THE LATTER TO COLD-HARDENING MATERIALS PRIOR TO THE HARDENING OR SETTING THEREOF.
