Tough curing liquid as well as preparation method and application thereof
The invention discloses a tough curing liquid as well as a preparation method and application thereof, and the tough curing liquid comprises the following raw material components in parts by weight: 70-80 parts of Portland cement, 20-30 parts of an admixture, 15-25 parts of an organic monomer, 1-2 parts of a cross-linking agent, 0.1-2 parts of an initiator, 5-10 parts of an expanding agent, 0.01-0.1 part of fiber and 70-100 parts of water, the admixture is one or two of coal ash or coal gasification slag micro powder with the particle size smaller than 45 microns; the organic monomer is an acrylamide monomer, and the cross-linking agent is N, N-methylene bisacrylamide; the initiator is ammonium persulfate or potassium persulfate. The expanding agent is a calcium oxide-calcium sulphoaluminate expanding agent, and the fibers comprise polypropylene fibers with the diameter of 18-48 microns and the length of 4-6 mm. The tough curing liquid is used for preparing tough cement soil for an underground diaphragm wall type curtain and can resist mining-induced stress disturbance, when mining-induced stress is spread to a diaphragm wall, a tough structural body formed in the wall body can generate elastic deformation, and the wall body is prevented from generating cracks or cracking or deformation damage.
本发明公开一种韧性固化液、制备方法及其应用，韧性固化液包括以下原料组分：以重量份数计，硅酸盐水泥水泥70～80份、掺合料20～30份、有机单体15～25份、交联剂1～2份、引发剂0.1～2份、膨胀剂5～10份、纤维0.01～0.1份和水70～100份，掺合料为粉煤灰或粒径＜45μm的煤气化渣微粉中的一种或两种；有机单体为丙烯酰胺单体，交联剂为N,N‑亚甲基双丙烯酰胺；引发剂为过硫酸铵或过硫酸钾。膨胀剂为氧化钙‑硫铝酸钙膨胀剂，纤维包括直径为18～48μm、长度为4～6mm的聚丙烯纤维。韧性固化液用于制备地下连续墙式帷幕用韧性水泥土，能够抵抗采动应力扰动，当采动应力传播到连续墙时，墙体内形成的韧性结构体将会发生弹性变形，避免墙体产生裂纹、开裂或变形破坏。
