<p><P>PROBLEM TO BE SOLVED: To provide a hydraulic composition which exhibits excellent flowability, nonshrinking property, and strength after being hardened, in various grouting (injection) methods in the civil engineering and construction field without using mineral matter fine powders such as waste fly ash, blast furnace slag, or the like and spherical aggregate, and which has flowability enough to be suitably filled into a joint sleeve for joining reinforcing bar and nonshrinking property for firmly unifying a construction region and is excellent in strength characteristics of a hardened body, in particular in a construction method for joining precast reinforced concrete members at a field. <P>SOLUTION: The hydraulic composition contains cement and a fine aggregate containing a ferronickel slag, wherein the ferronickel slag is characterized by containing particles having a particle size of 0.075-2.4 mm of 80 mass% or more and particles having a particle size less than 0.075 mm of less than 10 mass% in 100 mass% ferronickel slag. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
