<P>PROBLEM TO BE SOLVED: To obtain a spraying material which effects such advantages that a dust generation amount can be lessened, construction cost can be reduced because of reduced rebound, and a quick setting spraying cement concrete excellent in durability can be obtained in an environment susceptible to underground water, or the like, and also to provide a spraying construction method using the same. <P>SOLUTION: The spraying material comprises a cement concrete in which a fly ash is compounded in the cement, particularly in an amount of 10-100 pts. based on 100 pts. cement, and a liquid quick setting agent containing the elements of aluminum, sulfur and fluorine, an alkanolamine and the group 4A elements according to needs. The spraying construction method comprises using the spraying material, or comprises pressure-feeding the cement concrete and the quick setting agent individually, making confluent and mixing to spray. <P>COPYRIGHT: (C)2004,JPO |
