［摘要］通過(guò)鹵水侵蝕下的水泥基灌漿料抗壓性能試驗(yàn)，研究了水泥種類、水、水膠比、膠砂比、粉煤灰摻量、減水劑含量以及膨脹劑對(duì)水泥基灌漿料抗壓強(qiáng)度的影響，以及不同情況下耐蝕系數(shù)的差異性。試驗(yàn)研究表明，在大量試驗(yàn)基礎(chǔ)上配制的水泥基灌漿料初始流動(dòng)度基本上都在300mm以上；在合適的配合比情況下，以普通硅酸鹽水泥為主要成分的新型水泥基灌漿料在耐蝕性能上優(yōu)于硫鋁酸鹽水泥；水膠比0-35、粉煤灰摻量15%、聚羧酸減水劑含量1-3%、膠砂比控制在1:1的情況下，配制出的水泥基灌漿料初始流動(dòng)度為345mm，3d抗壓強(qiáng)度接近43MPa，28d抗壓強(qiáng)度接近69MPa，各齡期耐蝕系數(shù)均在0-9以上，且具有良好抗鹵水侵蝕性能。

Abstract:The compressive performance experiment of cement-based grouting material under brine erosion was carried out to study the influences of cement type, water, water-to-cement ratio, cement-to-sand ratio, fly ash content, water reducer content and expansive agent on compressive strength of cement-based grouting material, as well as the difference in corrosion resistance coefficient under different conditions. The experimental research shows that the initial fluidity of cement-based grouting material prepared on the basis of a large number of experiments is basically above 300mm; in the case of suitable mix ratio, the new cement-based grouting material with ordinary Portland cement as the main component has better corrosion resistance performance than sulphoaluminate cement; when water-cement ratio is 0-35, fly ash content is 15%, polycarboxylate water reducing agent content is 1-3%, and the ratio of cement-to-sand ratio is controlled at 1∶1, the initial fluidity of the cement-based grouting material is 345mm, and the  compressive strength at 3 days is close to 43MPa, and the compressive strength at 28 days is close to 69MPa, and the corrosion resistance coefficient of each age is above 0-9, and it has good resistance to brine erosion.

Keywords:cement-based grouting material; brine erosion; orthogonal experiment; compressive performance; corrosion resistance performance
