Microbial-erosion-resistant protective concrete and preparation method thereof
The invention relates to the field of protective concrete, and particularly discloses microbial-erosion-resistant protective concrete and a preparation method thereof. The microbial-erosion-resistant protective concrete is prepared from the following raw materials in parts by weight: 200-240 parts of cement, 800-930 parts of coarse aggregate, 600-700 parts of fine aggregate, 15-30 parts of micro powder, 110-170 parts of water, 2-8 parts of polycarboxylate superplasticizer, 7-18 parts of corrosion inhibitor and 5-12 parts of antibacterial particles; the preparation method of the microbial-erosion-resistant protective concrete comprises the following steps: step 1, preparing the corrosion-resistant agent and the antibacterial particles; and 2, uniformly premixing the water, the cement, the coarse aggregate and the fine aggregate, then adding the micro powder, the polycarboxylate superplasticizer, the corrosion inhibitor and the antibacterial particles, and uniformly mixing. The concrete prepared by the method has good bacteriostatic and bactericidal effects in reinforced concrete structures such as sewage discharge pipes, primary sedimentation tanks, aeration tanks, oxidation ditches, secondary sedimentation tanks and the like for conveying and treating sewage, has good corrosion resistance to microorganisms, and can keep excellent corrosion resistance in sewage containing sulfate.
本申请涉及防护混凝土领域，具体公开了一种耐微生物侵蚀防护混凝土及其制备方法，耐微生物侵蚀防护混凝土包括以下重量份的原料：水泥200‑240份，粗骨料800‑930份，细骨料600‑700份，微粉15‑30份，水110‑170份，聚羧酸减水剂2‑8份，耐蚀剂7‑18份，抗菌颗粒5‑12份；耐微生物侵蚀防护混凝土的制备方法包括以下步骤：步骤一、制备耐蚀剂和抗菌颗粒；步骤二、将水、水泥、粗骨料和细骨料预混均匀，然后加入微粉、聚羧酸减水剂、耐蚀剂和抗菌颗粒混合均匀。通过本申请制得的混凝土，在输送和处理污水的构筑物如排污管、初沉池、曝气池和氧化沟、二沉池等钢筋混凝土结构中均具有良好的抑菌杀菌作用，对微生物的耐侵蚀性佳，能够在含有硫酸盐的污水中保持优良的耐蚀性。
