EPOXIES IN CONCRETE CONSTRUCTION AND MAINTENANCE

THE WORK DONE BY THE MATERIALS AND RESEARCH DEPARTMENT OF THE CALIFORNIA DIVISION OF HIGHWAYS SINCE 1954 IS DESCRIBED IN ADAPTING EPOXY RESINS TO THE MAINTENANCE AND REPAIR OF CONCRETE HIGHWAYS AND BRIDGE DECKS. IT DISCUSSES HOW THE HIGH COEFFICIENT OF THERMAL EXPANSION OF CURED EPOXY MORTARS,WHICH CAUSES PORTLAND-CEMENT CONCRETE OVER WHICH THE EPOXY MORTARS ARE APPLIED TO RUPTURE IN TENSION, MAY BE NEUTRALIZED BY THE FORMULATION OF EPOXY MORTARS HAVING HIGH CREEP VALUES AT SUB-ZERO TEMPERATURES. THE FIRST USE OF ADHESIVES OF THE EPOXY-RESIN TYPE TO BOND NEW PORTLAND- CEMENT CONCRETE TO OLD PORTLAND-CEMENT CONCRETE WAS MADE BY THE MATERIALS AND RESEARCH DEPARTMENT.
