摘　　要：以亚糠基丙酮改性环氧树脂灌浆材料为基础作进一步研究，获得的弹性环氧树脂优化系列浆材的起始粘度在一个很宽的范围内（１０～１２０×１０－３Ｐａ·ｓ）变化，有良好的可灌性，而固结体的抗压强度（９０～１２０ＭＰａ）和粘结强度（＞４．０ＭＰａ）基本保持不变，适用于不同混凝土裂缝的固结补强。Further study was carried out based on epoxy grouting material modified by 2-furfurylidene methyl ketone.The results showed that the initial viscosity of the serial elastic epoxy grouting material varies over a wide range (10～120MPa.s). The material has good groutability and the compressive strength(90～120MPa) and bonding strength(4.0MPa) of the solid chunk remained constant which was suitable for consolidation and reinforcement of different concrete cracks. their application in several projects was successful.
