POLYMER RESINS AS ADMIXTURES IN PORTLAND CEMENT MORTAR AND CONCRETE

THIS REPORT COVERS THE STUDIES MADE ON TWO ADMIXTURES FOR CONCRETE THAT WERE INVESTIGATED PRIMARILY FOR THEIR USE AS OVERLAYS OR AS PATCHING MATERIALS FOR BRIDGE DECKS. THE FIRST, EPOXON, IS A MIXTURE OF POZZOLAN AND A TWO-COMPONENT EPOXY RESIN EMULSION. THE SECOND, TUFCHEM, IS AN "ORGANIC WATER-SOLUBLE POLYMER." WHEN COMPARED WITH NORMAL CONCRETE, IT WAS FOUND THAT: EPOXON MODIFIED CONCRETE EXHIBITED INCREASED STRENGTHS FOR CONCENTRATIONS OF 20 PERCENT EPOXY RESIN OR LESS BASED ON THE WEIGHT OF THE CEMENT, SATISFACTORY BOND-TO-CONCRETE, AND INCREASED RESISTANCE TO ATTACK BY SULFURIC ACID. TUFCHEM MODIFIED CONCRETE EXHIBITED INCREASED EARLY STRENGTH, INCREASED EARLY SHRINKAGE, AND DECREASED BOND-TO-STEEL AND HARDENED CONCRETE. BOTH MATERIALS SHOWED ADEQUATE FREEZE-THAW RESISTANCE, RESISTANCE TO SCALING, TO ABRASION, AND TO SKIDDING. /AUTHOR/
