Corrosion-resistant concrete drainage pipe and preparation method thereof
The invention relates to the technical field of building materials, in particular to a corrosion-resistant concrete drainage pipe and a preparation method thereof. The drainage pipe is composed of a reinforcement cage and a corrosion-resistant concrete pipe body. The corrosion-resistant concrete pipe body is prepared from the following raw materials in parts by weight: 150 to 180 parts of Portland cement, 260 to 300 parts of pottery sand, 320 to 360 parts of pebbles, 12 to 20 parts of shell powder, 25 to 40 parts of fly ash, 1.8 to 2.5 parts of polyvinyl alcohol fibers, 1.2 to 2.0 parts of sepiolite fibers, 8 to 12 parts of expanded perlite, 1.8 to 3.2 parts of silicone rubber powder, 1.0 to 1.5 parts of calcium formate, 1.2 to 2.0 parts of a corrosion inhibitor, 1.6 to 3.2 parts of a water reducing agent, 0.8 to 1.5 parts of a retarder, 2.8 to 4.2 parts of a pumping agent, 10 to 15 parts of a corrosion-resistant additive and 100 to 130 parts of water; the concrete drainage pipe prepared by the invention not only has good mechanical properties and impermeability, but also has certain antibacterial performance and corrosion resistance, the quality of the concrete drainage pipe is effectively ensured, and the service life of the concrete drainage pipe is also prolonged.
本发明涉及建筑材料技术领域，具体涉及一种耐腐蚀混凝土排水管及其制备方法；所述排水管由钢筋笼及耐腐蚀混凝土管体组成；所述耐腐蚀混凝土管体由以下重量份原料组成：150～180份硅酸盐水泥、260～300份陶砂、320～360份石子、12～20份贝壳粉、25～40份粉煤灰、1.8～2.5份聚乙烯醇纤维、1.2～2.0份海泡石纤维、8～12份膨胀珍珠岩、1.8～3.2份硅橡胶胶粉、1.0～1.5份甲酸钙、1.2～2.0份阻锈剂、1.6～3.2份减水剂、0.8～1.5份缓凝剂、2.8～4.2份泵送剂、10～15份耐腐助剂及100～130份水；本发明所制备的混凝土排水管不仅具有很好的力学性能及抗渗性能，同时还具有一定的抗菌性能及耐腐蚀性能，有效地保证了混凝土排水管的质量，也延长了其使用寿命。
