To analyze the influence law of curing conditions on the microstructure and compressive strength of cement emulsified asphalt mortar,two different curing conditions were set,including dry curing condition((25±2)℃,humidity(65±5)％)and wet curing condition((25±2)℃,humidity(90±5)％).The compressive strength,microscopic morphology,and pore radius distribution of CA mortar under different curing conditions were tested by compressive strength test,environmental scanning electron microscopy(SEM),and low-field nuclear magnetic resonance(NMR)respectively.The results showed that the compressive strength of CA mortar under dry curing condition was significantly higher than that of CA mortar under wet curing condition at all curing ages.The microstructure test results showed that both the water content difference of curing condition and the combined effect of asphalt significantly influenced the hydration process of CA mortar.Therefore,a unique organic-inorganic interpenetrating honeycomb structure was formed in the CA mortar under dry curing condition,which enabled it to obtain higher compressive strength even with a large porosity.Therefore,CA mortar should be avoided to be poured under wet environment as far as possible to improve its compressive strength.
