The results from the experiment are: the amount of all micro-powders that grain sizes are less 0.044 mm should be less than 35% in weight, and the value of coarse q and attenuate q should be respectively 0.23 and 0.32, and the additive amount of active a-alumina and calcium alumina cement should be respectively 7% and 4% in weight, meanwhile, the best dispersant is PMAA-NH4 in the non-microsilica system; while the value of two q should be respectively 0.21 and 0.29, the amount of active a-alumina, microsilica and calcium alumina cement should be respectively 6%, 2% and 4% in weight, the best dispersants are sodium hexamer taphosphate and Na2P3Oio in the microsilica system.

依照上述实验方法得出刚玉自流浇注料所必备的条件：刚玉自流浇注料中的细粉(-0.044mm)总量应小于35％；在无硅微粉系统中的Andreassen公式的粗端q值和细端q值分别为0.23和0.32，氧化铝微粉、水泥的最佳加入量是7％、4％，且所使用的分散剂为改性聚丙烯酸钠最好，而在含硅微粉系统中的Andreassen公式的粗端q值和细端q值分别为0.21和0.29，氧化铝微粉、硅微粉和水泥的最佳加入量为6％、2％和4％，最好合用三聚磷酸钠和六偏磷酸钠作为分散剂。

The two concepts of slag blending ratio in cement and admixing quantity of slag are liable to be confused when producing cement with clinker powder and slag powder .

采用熟料粉、矿渣粉拌和水泥生产工艺，往往易混淆水泥中矿渣粉配比和矿渣掺入量这两个概念。

Through measuring the gel time and the unconfined compression stre- ngth of cement-waterglass-clay specimen, this paper, using orthogonal method, analyzes the effect of different water-cement ratio, different admixing quantities of waterglass and different clay content on specimen strength and presents the optimal dispensation formula for two-fluid process of cement-waterglass.

本文通过水泥—水玻璃—粘土试件凝胶时间的测定及无侧限抗压强度测定，用正交方法分析了不同水灰比、不同水玻璃掺量及不同粘土含量对试件强度的影响，提出了水泥—水玻璃双液浆的最优配方，基本解决了旋喷施工时造成的基础瞬时沉降问题，为旅喷注浆的设计与施工提供了依据。
