PROBLEM TO BE SOLVED: To provide a liquid expansive admixture free from problems that (1) dusting occurs easily in preparation work, (2) the long term storage is difficult because of its high hygroscopicity, (3) it is hard to be dispersed after water is fed or the like which are observed in a hydration expansive admixture, exhibiting high expansive performance and hardly causing the fluctuation of the expansive performance. SOLUTION: The liquid expansive admixture is particles having free quick lime as an active ingredient and contains 100 pts.wt. particles having a coating film layer comprising calcium hydroxide (CH) and magnesium hydroxide (MH) in the ratio (MH/CH) of 0.01-0.1 and 30-100 pts.wt. organic liquid substantially inactive against calcium oxide.
