Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a low cost acidic rain resistant concrete capable of keeping strength as a concrete structure and exhibiting acid resistance to acidic rain having pH 3.0-5.6 and a composition to be a raw material thereof. SOLUTION: The acidic rain resistant concrete composition includes a binder comprising early strength Portland cement and flyash, aggregate and water, wherein the quantity of the flyash in the binder is 38-42 mass% and the percentage of water to binder 38-42 mass%. The acidic rain resistant concrete composition is used for various kinds of the concrete structures such as bridges and dams easily affected by the acidic rain. COPYRIGHT: (C)2010,JPO&INPIT
