摘　　要：丙烯酸盐注浆材料形成的固化物具有吸水膨胀、失水收缩的特性。试验研究表明,丙烯酸盐注浆材料形成的固化物稳定的失水收缩率可达到71.96%~90.03%,初始收缩速度和干缩率随着掺水量的增加和A/B料配比的减小而增大。本研究结果对正确认识丙烯酸盐注浆材料的特性和应用场合具有指导意义。The solid formed by acrylate grouting material has the characteristics of water expansion and dehydration shrinkage. The test results show that the stable water loss shrinkage of solid formed by acrylate grouting material is 71.96%~90.03%, the initial shrinkage rate and dry shrinkage rate increase with the increasing of water content and the decrease of A/B ratio. The results have guiding significance for correctly understanding the characteristics and application occasions of acrylate grouting materials.
