PROBLEM TO BE SOLVED: To provide a slag stimulant which easily gives a high strength development without causing remarkable coagulation and curing delay even in a ≡ slag hydraulic composition in which ≥50 mass% of cement is replaced by a slag powder, in a hydraulic composition in which part of the portland cement is replaced by a slag powder, and further gives the high strength ≡ slag hydraulic composition satisfying the standards as high strength concrete, and to provide the ≡ slag hydraulic composition using the stimulant.SOLUTION: The slag stimulant includes &bgr;-type gypsum hemihydrate (E) and anhydrous gypsum (F) in which the mass ratio (E/F) =0.3-1. Moreover, the ≡ slag hydraulic composition includes 4-10 pts.mass of the stimulant, 20-100 pts.mass of a portland cement clinker ground product, and 100 pts.mass of slag powder. |
