Beschreibung
Zusammenfassung:	The present invention provides a composition for ultra-strength grout materials using a binder for ultra-strength grout materials, a method for manufacturing the same and the binder for ultra-strength grout materials which comprises: 48-58wt% of normal Portland cement; 10-30wt% of blast furnace slag high-blaine; 15-25wt% of silica fume, and 3-7wt% of anhydrous gypsum. The binder for ultra-strength grout materials facilitates refilling a space formed between an outer steel plate and an inner steel plate regardless of size of safe and ATM machines, enhances workability, and maximizes a function of theft prevention for safe and ATM machines by obtaining ultra-high strength, shock resistance, heat resistance, and refractoriness.
