Abstract
Bisphenol A-type epoxy resin reinforced by TiO2 with different dosages (0, 1%, 3%, 5%) was for the first time used as a polymeric admixture to prepare ordinary Portland cement (OPC) mortars in this study. Tensile strength of the TiO2/epoxy resin composite, and flowability, compressive strength and flexural strength as well as the bonding strength of OPC mortars were measured. Scanning electron microscopy (SEM) was also carried out to observe the interfacial transition zone (ITZ) between sand and OPC paste, and the bonding interfacial transition zone (BITZ) between OPC mortar (either modified by the epoxy resin or not) and a substrate material. Results showed the tensile strength of the TiO2/..
