Corrosion-resistant concrete material and preparation method thereof
The invention relates to the technical field of concrete materials, in particular to a corrosion-resistant concrete material and a preparation method thereof. The corrosion-resistant concrete materialis prepared from the following components in parts by weight: 90 to 110 parts of Portland cement, 70 to 100 parts of water, 170 to 230 parts of gravel, 120 to 140 parts of sand, 20 to 30 parts of flyash, 11 to 16 parts of additive, 2 to 5 parts of composite water reducing agent and 10 to 15 parts of calcium oxide-calcium sulphoaluminate composite expanding agent. The corrosion-resistant concretematerial has good corrosion resistance, impermeability and compressive strength and is long in service life; the preparation method is simple and efficient, operation and control are convenient, theproduct quality is stable, and industrial production is facilitated.
本发明涉及混凝土材料技术领域，具体涉及一种耐腐蚀混凝土材料及其制备方法。所述耐腐蚀混凝土材料包括以下重量份的组分：硅酸盐水泥90‑110份、水70‑100份，碎石170‑230份、砂120‑140份、粉煤灰20‑30份、外加剂11‑16份、复合减水剂2‑5份、氧化钙‑硫铝酸钙复合膨胀剂10‑15份。本发明耐腐蚀混凝土材料具有良好的耐腐蚀性、抗渗性和抗压强度，使用年限长，其制备方法简单高效，操作控制方便，产品质量稳定，利于工业化生产。
