Abstract：Alkaline Redox Potential Water(ARPW)with different pH values was prepared by diaphragm electrolyzer,and its storage stability was tested.The hydration heat release characteristics,compressive strength and flexural strength of ARPW mixed slag geopolymer mortar samples were studied.The results showed that the higher the initial alkalinity of ARPW,the better the sta-bility of pH value.ARPW can accelerate the hydration process of slag geopolymer,which is characterized by shortening the induc-tion period,increasing the hydration heat release rate and increasing the cumulative hydration heat release.ARPW can significantly improve the 3 d and 28 d compressive and flexural strength of slag geopolymer under low alkali equivalent,and the early enhance-ment effect is more obvious.Increasing the concentration of NaCl electrolyte can shorten the electrolysis time of ARPW preparation and improve its enhancement effect.
