The invention discloses corrosion-resistant concrete, which is prepared from the following raw materials in parts by weight: 295 to 560 parts of Portland cement, 30 to 65 parts of sodium fluosilicate, 60 to 130 parts of acid-resistant powder, 655 to 890 parts of coarse aggregate, 280 to 475 parts of fine aggregate, 50 to 75 parts of manganese slag, 55 to 78 parts of penetrating agents, 150 to 165 parts of water and 6 to 9 parts of water reducing agents. According to the concrete disclosed by the invention, the filling property of each component is good, and gaps among particles of each component are reduced, so that the total porosity of the concrete is reduced, the concrete is more compact, the corrosion of the concrete can be prevented or slowed down, the corrosion resistance is stable, the effect is lasting, and the mechanical property, the impermeability and the corrosion resistance of the concrete are remarkably improved.
本发明公开了一种耐腐蚀性的混凝土，该混凝土包括以下重量份原料：硅酸盐水泥295‑560份、氟硅酸钠30‑65份、耐酸性粉料60‑130份、粗骨料655‑890份、细骨料280‑475份、锰矿渣50‑75份、渗透剂55‑78份、水150‑165份，减水剂6‑9份。本发明混凝土中各组分填充性好，减小各组分颗粒之间的空隙，从而减小混凝土总孔隙率，使混凝土更加密实，可阻止或减缓混凝土腐蚀，抗腐蚀性能稳定且效果持久，并显著提高混凝土的力学性能、抗渗性和耐腐蚀性。
