This study is a continuation of the published research studies relevant to self-compacting geopolymer mortar (SCGM) prototype using fly ash. The aim of this study was to investigate the effect of fly ash quantity on the rheological properties of SCGM. The flow properties include relative flow area (G_m) and relative funnel speed (R_m) is determined with the variation of fly ash to sand ratio (FA/S), volume of water to powder ratio (Vw/Vp), and superplasticizer to powder ratio (Sp/P). The test results exhibited that the increase in FA/S from 0.5 to 1.0 positively affected the G_m and R_m of SCGM. The maximum G_m of 10.90 and R_m of 1.43 were obtained for the SCGM mix having FA/S of 1.0, Vw/Vp of 1.02, and Sp/P of 3%. Overall, test results exhibited that with an increase in FA/S comparable flow properties of SCGM were achieved even at lower Vw/Vp and Sp/P. The recommended boundary for SCGM is proposed by comparing the experimental test result of this study with previous studies.

这项研究是已发表的与使用粉煤灰的自密实地质聚合物砂浆（SCGM）原型相关的研究的延续。本研究的目的是研究飞灰用量对 SCGM 流变性能的影响。流动特性包括相对流动面积（G _m）和相对漏斗速度（R _m）由飞灰与砂的比例（FA/S）、水与粉末的体积比（Vw/Vp）和高效减水剂的变化决定与粉末的比例（Sp/P）。测试结果表明，FA/S从0.5增加到1.0对SCGM的G _m和R _m产生积极影响。对于FA/S为1.0、Vw/Vp为1.02和Sp/P为3%的SCGM混合物，获得了10.90的最大G _m和1.43的R _{m 。}总体而言，测试结果表明，随着 FA/S 的增加，即使在较低的 Vw/Vp 和 Sp/P 下，SCGM 也能实现可比的流动特性。通过将本研究的实验测试结果与之前的研究进行比较，提出了 SCGM 的推荐边界。
