引用本文摘 要：為了滿足道路半剛性基層隱含裂縫的灌漿要求，研究了一種快硬硫鋁酸鹽水泥與普通硅酸鹽水泥復配的水泥基灌漿材料；同時輔以減水劑對不同配合比灌漿材料的灌漿特性進行了研究。結果表明，得到15min內流動性好、30min達到初凝、2h內強度增長快的水泥基灌漿材料的最佳配合比為水泥∶水∶減水劑=1∶0.35∶0.015，其中快硬硫鋁酸鹽水泥與普通硅酸鹽水泥的比值為0.5625，AS氨基磺酸系減水劑與FDN萘系減水劑1:1復合使用。 Abstract: In order to meet the grouting requirement of the concealed crack in road base, characteristics of grouting for the grouting materials including water reducer of different proportion of mixture are researched. The results show that the optimum mixture ratio of the cement based grouting material is cement, water, water reducer =1∶0.35∶0.35. The cement based grouting material has good liquidity within 15 minutes, achieves initial setting in 30 minutes and has quickly increasing strength within 2 hours. The ratio of the sulphoaluminate cement and Portland cement of the grouting materials is 0.5625∶1. The water reducer ratio of the AS amino sulfonic acid-based and FDN naphthalene formaldehyde is 1:1.
