为利用盾构泥砂成功制备出高性能同步注浆材料，采用膨润土、凹凸棒黏土、羟丙基甲基纤维素、羟乙基纤维素、FDN 减水剂、聚羧酸减水剂与葡萄糖酸钠进行复配，优选配方组成，研制出高性能同步注浆材料专用外加剂HMA。结果表明，掺加HMA配制出的同步注浆材料工作性能好，初始流动度可达210 mm，流动度经时损失极小，能有效防止管片上浮，稠度值为10 cm左右，泌水率几乎为0，抗水分散效果好，28 d水陆强度比可达0．90以上。说明HMA外加剂非常适合用来配制高性能同步注浆材料。

Bentonite,attapulgite clay,hypromellose cellulose,hydroxyethyl cellulose,FDN water reducer and polycar-boxylate water reducer are used to be compounded with sodium gluconate to develop HMA additive,so as to prepare high-performance simultaneous grouting material on basis of mucks produced in shield tunneling.The test results show that the simultaneous grouting material with HMA additive has good workability,with the initial fluidity being up to 210 mm and the fluidity loss being very small;the simultaneous grouting material can prevent the segments from up-floating effectively;the simultaneous grouting material has a consistence value of around 10 cm,a bleeding rate of almost 0 and good resistance to water dispersion,and the simultaneous grouting material has a 28 d amphibious strength ratio up to more than 0.90.These results indicate that HMA additive is very suitable for preparing high-performance simultaneous grouting material.
