Abstract：Adopting emulsified asphalts to modify high-strength mortar,the reasonable water yield of modified mortar with different dosage is studied on the condition of keeping mortar liquidity and analyzing the charge distribution of modified mortar particle.Micro-calorimeter is used to study the hydration heat of cement mortar and analyze the solidification characteristics of modified mortar.Drawing the bending force and the deflection curve according to the compressive,bending and bending deflection test of modified mortar.The optimal content of emulsified asphalt is determined by analyzing the toughening and brittle reduction effect of modified high strength mortar with flexural/compressive ratio and flexural absorption method.The result shows that emulsified asphalt modified high strength mortar not only has obvious toughening and brittle reduction effect,but also has high strength and self-leveling characteristics.
