[PROBLEMS] A hydraulic composition containing a high amount of blast furnace slag, which has a setting time equivalent to that of ordinary cement, good strength development, and can suppress neutralization, despite the use of a large amount of blast furnace slag. The purpose is to get things. The present invention can be solved by using a hydraulic composition using two or more kinds of stimulants having different rates of elution of calcium ions as a stimulant in a combination of blast furnace slag fine powder and limestone fine powder.
