Anti-permeability reinforced grouting material for fractured rock mass under flowing water condition and slurry production method
The invention provides an anti-permeability reinforced grouting material for fractured rock mass under a flowing water condition and a slurry production method. The anti-permeability reinforced grouting material comprises sulphoaluminate cement, metakaolin, mineral powder, fly ash and a plastic expanding agent. According to the invention, the effect that metakaolin in the anti-permeability reinforced grouting material consumes large-grain crystal products like calcium hydroxide is utilized to generate finer gel products; meanwhile, the mineral powder and fly ash have a micro-powder "filling effect", so that pores in the structure of the stone body after slurry hardening are reduced, the structure is compact, the strength of the stone body is improved, and the impermeability of the stone body is improved. The raw materials are easy to purchase, the cost is low, the mortar mixing ratio is simple, the slurry production method is simple and convenient, the impermeability is high, and the stone strength is high.
本发明提供了一种用于动水条件下裂隙岩体的抗渗加强型注浆材料及浆液生产方法，所述抗渗加强型注浆材料包括硫铝酸盐水泥、偏高岭土、矿粉、粉煤灰和塑性膨胀剂。本发明利用抗渗加强型注浆材料中偏高岭土消耗氢氧化钙这类大晶粒晶体产物的作用，利用这一作用，生成更细小的凝胶产物；同时，矿粉和粉煤灰具有微粉“填充作用”，使得浆体硬化后的结石体的结构中的孔隙变小，结构密实，提高结石体的强度，增大结石体的抗渗性。本发明原料易于采购且成本较低，砂浆配和比简单，浆液生产方法简便，抗渗能力强，结石体强度高。
