REPAIR OF CAVITATION DAMAGE IN CONCRETE WITH EPOXY-RESIN MATERIALS

PORTLAND CEMENT CONCRETE IN THE FLOOR OF THE OUTLET WORKS AT FORT RANDALL DAM, PICKSTOWN, S.D., WAS DAMAGED BY CAVITATION FROM HIGH-VELOCITY WATER FLOW. AN ENGINEERING STUDY INDICATED THAT REPAIR COULD BE ACCOMPLISHED MOST ECONOMICALLY WITH EPOXY-RESIN MATERIALS. MIX PROPORTIONS WERE DEVELOPED IN THE MISSOURI RIVER DIVISION LABORATORY OF THE CORPS OF ENGINEERS FOR AN EPOXY-RESIN CONCRETE, AN EPOXY-RESIN MORTAR, AND AN ARMOR COATING. THE OMAHA DISTRICT OFFICE OF THE CORPS OF ENGINEERS FURNISHED COMPREHENSIVE INSTRUCTIONS AND PACKAGED MATERIALS TO FIELD PERSONNEL FOR ACCOMPLISHING THE REPAIR AT THIS REMOTE LOCATION. THE DAMAGE WAS SUCCESSFULLY REPAIRED BY FIELD PERSONNEL HAVING LITTLE PREVIOUS EXPERIENCE WITH EPOXY-RESIN MATERIALS. THE MATERIALS, MIXES, AND PROCEDURES USED ARE DESCRIBED IN DETAIL, INCLUDING HEALTH AND SAFETY PRECAUTIONS. AN INSPECTION WAS MADE AFTER THE REPAIRED AREA HAD BEEN UNDER WATER FOR 5 YEARS, AND THE REPAIR WAS FOUND TO BE PERFORMING SATISFACTORILY. SUGGESTIONS FOR FUTURE WORK OF THIS NATURE ARE GIVEN. /ACIJP/
