Reusing Goldmine Tailings In Cement Mortars

7 days. mortar using 25 tailings, that are t25.1, t25.2 and t25.3, the lowest compressive strength is t25.2 both at the age of 7 days and at 28 days. this is because the tailings mortar casted in a saturated surface dry condition so that the ratio of watercement samples t25.2.
