摘　　要：为研究EFS土壤固化剂改性生土在房建工程方面应用的可能,设计12种固化土配合比方案,对固化土试件的7d、28d无侧限抗压强度、水稳定性进行试验研究。结果表明,C3组试件(5%水泥+0.015%EFS土壤固化剂)抗压性能最好,高出新墨西哥州土坯与夯土建筑规范规定34.7%,B2、B3、B4、C3、C4、D4组试件满足规范对7d抗压强度的要求;除B1、D4试件水稳定性较差,其余组试件均具有良好的水稳定性;EFS土壤固化剂可促进水泥与土颗粒胶结成整体,从而减少水泥使用量,在提高房建性能同时,降低对环境的污染。In order to study the possible application of EFS soil curing agent modified raw soil in housing construction engineering,12 kinds of solidified soil mixture ratio schemes were designed,and the unconfined compressive strength and water stability of solidified soil specimens were tested for 7d and 28d.The results show that group C3(5% cement +0.015%EFS soil hardener) has the best compressive strength,which is 34.7% higher than new Mexico Adobe and rammed-earth building Code.Group B2,B3,B4,C3,C4,and D4 meet the requirements of the code for 7d compressive strength.Except for B1 and D4,the water stability was poor,and the other groups had good water stability.EFS soil hardeners promote cement to soil particles as a whole,thereby reducing cement usage,improving building performance and reducing environmental pollution.
