添加剂YDS能"活化""惰性"稀释剂，在此基础上开发成功的新型高渗透性环氧系灌浆材料，具有极高的渗透性，对常见介质有较高的亲和力，固结体的力学性能优良而且成本较低，适用于大坝的低渗透软弱基础固结补强和混凝土裂隙的补强防渗等。并举例说明了这种浆材的实际使用效果。

 A new chemical grouting material, developed by employing the study result of an additive YDS which can activate the inert diluent , is introduced in the paper .It possesses very high permeability, strong affinity t o conventional media, excellent mechanical properties of consolidation and low cost price. It is suitable for strengthening low permeable ,soft foundation and concrete cracks' seepage control and reinforcement. Some illustrations are provided for explicating its practical usage effects.
