The purpose of this study was to examine the influence of various polymeric materials on the adhesion characteristics of a rapid setting, minimum defect mortar based upon a blend of calcium sulfoaluminate (CSA) cement and ordinary Portland cement (OPC). Four different polymer powders were added to the base mortar at a polymer/cement ratio (p/c) of 0.15. The water/cement (w/c) ratio remained constant for all mortars at 0.42. The polymeric materials consisted of an acrylic polymer powder with Tg=-10°C, a styrene butadiene rubber (SBR) polymer powder with Tg=15°C and two vinyl acetate/ethylene (VAE) polymer powders, one with Tg=-7°C and the other with Tg=20°C. Mortars were tested for direct tensile strength following ASTM C307 and pull-off strength following a variant of ASTM C1583 after curing for either 24 h or 13 days at ambient laboratory temperature of 23°C. Mortars were cast over concrete, wood, metal and glass substrates. Pull-off tests over concrete substrate resulted in substrate failure for all polymer modified mortars. Pull-off tests cast over wood, glass and metal substrate materials highlighted the SBR polymer for demonstrating the poorest adhesion performance. Statistical analysis was performed with Minitab software.
