中文摘要：

采用水化热-时间曲线和电阻率-时间曲线研究沥青乳液加料顺序引起CA砂浆早期强度不同的原因，研究结果表明，先加沥青乳液对水泥具有较强的缓凝作用，而后加沥青乳液的缓凝作用较弱，这是导致后加沥青乳液能显著提高CA砂浆早期强度的根本原因。

英文摘要：

Effect of mixing sequence of asphalt emulsion on strength development of CA mortar was studied by calorimetry and electrical resistivity measurements. Results indicated that addition of asphalt emulsion before cement had a much greater retarding effect on the hydration of cement compared to addition of asphalt emulsion after cement, which was the fundamental cause influencing the early strength development of CA mortar.
