The modification effects of the cement and the water-based epoxy resin on the asphalt emulsified mortar are studied. The result shows that with the cement content 30% and water-epoxy resin emulsified content 30%, the modified asphalt emulsified mortar which can replace cement mortar meets the demands of the relative criterions. When the temperature reaches 140°C, both the tensile bond strength and the shear bond strength decrease to 0.1 MPa. So it is feasible to recycle the decorative stone .The micro-analysis of the modified mortar are investigated by using IR and TGA-DTA, and its modification mechanism is also discussed.
A new type modified asphalt emulsion mortar is studied in order to find out the most favorable materials for the recycling of decorative stone. Through some experiments, by comparing the cement and water-epoxy resin emulsion mixed separately or together on the performances of emulsified asphalt mortar, the result shows that cement content 30% and water-epoxy resin emulsion content 30% mixing together is better than mixing separately. Besides, the paper has made a systematic study on the comprehensive performance, the result shows that with excellent performances, the modified asphalt emulsion mortar which can replace cement mortar meets the demands of the relative criterions. When the temperature reaches 140°C, both the tensile bond strength and the shear bond strength decrease to 0.1 MPa. So it is feasible to recycle the decorative stone.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
