摘　　要：利用工业废渣(矿渣、钢渣、粉煤灰)和水玻璃制备出具有不同凝胶时间(3～300 s)、高固结强度(～25 MPa)和结石率可达100%的双液注浆材料,使工业废渣再生资源化,并减少灌浆水泥的消耗量,为注浆材料的“绿色”和高性能化提供了一种选择.研究结果表明:随着水玻璃模数的增加,浆液凝胶时间先减小后增大,浆液固结强度先增大后减小;随着水玻璃掺量(体积分数)的增加,浆液凝胶时间保持延长趋势,而固结强度则先增大后减小;随着粉煤灰的加入,浆液凝胶时间延长.当工业废渣双掺或三掺时,无水泥熟料注浆材料体系较单掺工业废渣无水泥熟料注浆材料体系具有更合理的颗粒级配效应和更高的固结强度.The feasibility for using water glass and industry waste slag （blast furnace slag, steelmaking slag, fly ash） to prepare double solution grouting material without cement clinker was investigated. The results indicate that the double solution grouting material without cement clinker features different gel-time （3-300 s）, high concreted strength （-25 MPa） and 100% stone rate. With the water-glass modulus increasing, the gel-time of grouting paste first decreases and then increases, and the concreted strength first increases and then reduces. With the water-glass dosage increasing, the gel-time of grouting paste increases, and the concreted strength first increases and then reduces. With the fly ash added, the gel-time of grouting paste increases. When two or three kinds of industry waste slag are used in the grouting system, the grouting paste has better particle gradation and higher concreted strength. This research offers a choice for the green and high performance of double solution grouting materials, in which industry waste slags are recycled and used fully and the wastage of the grouting cement is cut down.
