PROBLEM TO BE SOLVED: To provide a composition for mortar or concrete which is excellent in salt damage resistance performance and molding produced by the same.SOLUTION: A composition for mortar or concrete includes blast furnace slag fine aggregate and a binder containing blast furnace slag fine powder and Portland cement. The content of the blast furnace slag fine aggregate to total amount of fine aggregate is at least 66.7% in mass ratio. By using the blast furnace slag fine aggregate in fine aggregate, mortar or concrete is elaborated and increased in strength, so that the infiltration of chloride ions can be controlled. |
