<p><P>PROBLEM TO BE SOLVED: To provide an acid-resistant concrete member usable under environment exposed to an acidic fluid. <P>SOLUTION: The acid-resistant concrete member is formed by placing concrete containing a binder (B), water (W), fine aggregate (S), coarse aggregate (G1 and G2) and an admixture (SP) in a form. The binder (B) comprises cement (C), PFBC (Pressure Fluidized Bed Combustion) ash (PFBC) and blast furnace fine powder (BF). In the embodiment, the PFBC ash (FPBC) and the cement (C) are blended so that the PFBC ash (PFBC) occupied in the binder (B) is≥40 mass% and≤50 mass% and the content of the cement (C) occupied in the binder (B) is≥20 mass% and≤30 mass%. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
