粉末状高强高耐水土体固结剂（ＨＥＣ） ，不仅可用来固化各种土体，使之具有强度、耐水性和耐久性，而且还可以作为混凝土的胶凝材料，其特点是掺量少、固结范围广、固结体强度高、水稳定性好、使用简便、就地取材、降低工程造价、缩短施工周期等。利用ＨＥＣ 对三峡风化砂、碎石屑等弃渣和毛料进行了固化试验研究，结果表明，ＨＥＣ 的固结体具有良好的物理力学性能和耐久性能，可用于路基、路面、挡墙、护坡、护砌等工程。ＨＥＣ 的开发为合理而有效地利用三峡工程弃渣开辟了一条新途径 Powder high strength and high water-resistant soil solidifying agent (HEC), not only can be used to cure various soil, so that it has the strength, water resistance and durability, but also as a concrete cementitious material, which is characterized by low dosage , A wide range of consolidation, high consolidation strength, good water stability, easy to use, local materials, reduce project cost and shorten the construction period. HEC was used to test the solidified sand and debris of the Three Gorges. The results show that the solidified HEC has good physical and mechanical properties and durability. It can be used in roadbed, pavement, retaining wall, slope protection, Conservancy and other projects. The development of HEC has opened up a new avenue for the rational and effective utilization of the waste from the Three Gorges Project
