In this study, the effect of electrolyzed cathode water on the properties and hydration promotion of mortar was investigated by using two kinds of different electrolyzed water and ordinary tap water. The results showed that the single K+ electrolyzed water in mortar can promote and stimulate the cement hydration to produce more Ca(OH)2 amount, leading to a higher strength of mortar than ordinary tap water mortar. In contrast, the compound Na+-K+ electrolyzed water had a bad effect on cement hydration reaction and strength improvement of mortar for the long-term age.
