Workability and strength of coarse high calcium fly ash geopolymer
TL;DR: In this article, the basic properties viz., workability and strength of geopolymer mortar made from coarse lignite high calcium fly ash were investigated, and the results revealed that the workable flow of the geopolymers was in the range of 110 −±5% −135 −± 5% and was dependent on the ratio by mass of sodium silicate to NaOH and the concentration of NaOH.
