MATERIALS AND PROCEDURES FOR THE REPAIR OF SPALLS IN CONCRETE

OLD AND NEW MATERIALS USED FOR REPAIRING DAMAGED OR DETERIORATED CONCRETE ARE STUDIED AND EVALUATED. LARGE DAMAGED AREAS CAN BE SUCCESSFULLY AND ECONOMICALLY REPAIRED USING A GOOD QUALITY, LOW SLUMP, PORTLAND CEMENT CONCRETE BONDED TO THE OLD CONCRETE WITH AN EPOXY RESIN GROUT. SMALL SPALLS AND SPECIALIZED AREAS CAN BE BEST REPAIRED WITH AN EPOXY RESIN MORTAR. SURFACE PREPARATION MUST BE COMPLETED AND MANUFACTURER'S DIRECTIONS FOR MIXING AND CURING FOLLOWED. EXPANSIVE CEMENTS AND NEW MODIFIED LATEX MATERIALS SHOW PROMISE, BUT FIELD DATA IS INSUFFICIENT TO DRAW CONCLUSIONS.
