PATCHING AND GROUTING MATERIALS FOR PORTLAND CEMENT CONCRETE

A STANDARD SERIES OF TESTS FOR EVALUATING CONCRETE PATCHING COMPOUNDS WAS DEVELOPED. NINTEEN COMMERCIAL PRODUCTS WERE EVALUATED AS COMPARED TO TYPE III CEMENT MORTAR AND TESTED FOR THE FOLLOWING PROPERTIES: SET TIME, EXPANSION WHEN SOAKED 24 HOURS, DRYING SHRINKAGE, PERCENT CHLORIDES, PERCENT SULPHATE, ABRASION RESISTANCE, AND COMPRESSIVE STRENGTH AT ONE HOUR, 4 HOURS, ONE DAY, 3 DAYS, AND 28 DAYS. THESE PRODUCTS HAD FAST SETTING AND EARLY STRENGTH GAIN CHARACTERISTICS. SEVERAL PRODUCTS WERE TESTED FOR CORROSION PROPERTIES WHEN USED IN CONTACT WITH REINFORCING STEEL. IN ADDITION, 15 OF THE PRODUCTS WERE PLACED IN A FIELD INSTALLATION IN THE WHEEL PATH IN THE HEAVILY TRAVELED LANE WHERE THEY WERE SUBJECTED TO FREEZING- THAWING, SNOW, TIRE-CHAIN TRAFFIC, AND SUMMER TRAFFIC. INDUSTRY NEEDS TO PRODUCE A MORE UNIFORM PRODUCT. PRODUCTS MARKETED CHANGE OFTEN AND MATERIALS TESTED ARE OFTEN NOT WHAT IS MARKETED LATER. MATERIALS SHOULD BE DEFINED FOR VARIOUS APPLICATIONS AND APPROPRIATE SPECIFICATIONS SHOULD BE ADOPTED. /AUTHOR/
