Abstract
This paper presents the research results on the effect of the concentration of NaOH alkaline solution of 10M, 12M, 14M and 16M respectively and the ratio of the alkaline-activated solution (NaOH and Na2SiO3) to fly ash (FA): DD/FA = 0.35; 0.40 and 0.45 to the strength of geopolymer mortar. Geopolymer mortar samples curing at different temperatures were also studied. Through the experimental results, the optimal ratio of DD/FA = 0.4 was selected, achieving the maximum compressive strength of GPM mortar at 28 days of age, satisfying the technical requirements of the designed GPM mortar
