• To investigate the modification of PAE-modified cement mortar with high flowability and fracture mode of adhesive strength properties in tension, experimental parameters were set as PAE solid-cement ratio (P/C) and cement: fine aggregate (C:F) and experiments regarding unit weight, flow, consistency change, crack resistance and segregation were conducted. Adhesion in tension was measured to comprehend the properties and fracture mode in tensile load. It was found to be superior to that of resin based materials such as polyurethane and epoxy which showed entire loss of consistency in an elapsed time of 90min. after mixing. Adhesive strength in tension increased with continuity during curing period and showed the maximum in the case of C:F=1:1 and P/C=20%.
