The result of research indicates that curing condition can apparently influence the bond strength of mortar; water reducer superplasticizer can significantly improve the bond strength of mortar, polymer latex powder cannot increase the bond strength of mortar, but decrease the influence of curing condition on the bond strength of mortar.
Keywords: waterreducer; polymer; curing condition; bond strength
