INVESTIGATION OF THE USE OF RESIN-BASED MEMBRANE CURING AND BONDING COMPOUNDS ON HORIZONTAL CONSTRUCTION JOINTS
Longitudinal semicylindrical 6- by 12-in. (152- by 305-mm) specimens for bonding comparisons were made from concrete containing 3/4-in. (19-mm) maximum size limestone aggregate with a slump of 1-1/2 plus minus 1/2 in. (38 plus minus 13 mm) and an air content of 5.5 plus minus 0.5 percent. Some of the surfaces of the specimens were sandblasted and some were treated with a pigmented resin-based, membrane- forming curing and bonding compound containing chlorinated rubber. After the treatment, the other half of each specimen was filled with concrete. Splitting tensile tests on the specimens were conducted at 28 days, the results of which indicated that the splitting tensile strengths of the joint surfaces treated with the membrane were approximately 20 percent lower than those sandblasted.
