Abstract

A novel in-situ synthetic method is developed for fabrication of inorganic-organic hybrid structured TiO2/Epoxy resin composite without adding any surfactants. It is discovered for the first time that the inorganic-organic micro-structured TiO2/Epoxy composite can be homogeneously dispersed in one type of alkali-activated binders: alkali-activated slag/fly ash (AASF) pastes with slag/fly ash at 50/50. Besides, it is found that TiO2/Epoxy composite is capable of enhancing the mechanical properties including compressive and flexural bending strengths, improving porous structures and reducing drying shrinkage of the AASF paste. Moreover, scanning electron microscopy results showed that the AASF..
