- Abstract
Cement-based colored mortar was modified by waterborne epoxy resin to prepare a kind of colored pavement material with excellent mechanical properties and economy. The best mix ratio and pavement performance of composite materials was studied by the flexural strength test, the compressive strength test, the bonding strength test, the slip resistance performance test and the color durability test. The effect of waterborne epoxy resin and fly ash on hydration products of cement was studied by scanning electron microscope (SEM) microscopic test. The results show that the mechanical properties of modified mortar are the best when the content of fly ash is 10% and that of waterborne epoxy resin is 10%. The pendulum friction coefficient (BPN) of the modified mortar is basically maintained in 55 ~ 80, and it's slip resistance performance is excellent. The addition of waterborne epoxy resin increases the bonding properties, acid corrosion resistance properties and late flexural strength of cement mortar, but reduces its compressive strength. An appropriate amount of fly ash can increase the late flexural and compressive strength of cement mortar.
