LABORATORY AND FIELD EVALUATION OF POLYMERIC CAVITATION EROSION-RESISTANT MATERIALS ON CONCRETE

Fifteen polymeric coatings for protecting concrete against cavitation erosion were evaluated. Eight of these materials were found to be cavitation erosion resistant. Five of these eight materials were polyurethane sheet materials: the other three were a liquid-applied polyurethane, a neoprene sheet, and a liquid-applied neoprene. The materials were evaluated by coating mortar specimens with the materials and determining the adhesive bond strength. Those materials which were bonded successfully to the mortar and which showed promise for field application were evaluated further by determining the durability of the bond and the material to water immersion. A nondestructive test method (ultrasonic) was evaluated to determine optimum application of materials in the field.
