Dec 01, 2017 Type of aggregate shows great effect on flow table test results of geopolymer mortar. Using crushed limestone resulted in low mortar flow while combined sand shows better flow. On the other hand, geopolymer mortar including natural sand shows better flowability compared to other aggregates. The effect of grading was also verified experimentally.
