High-durability concrete for drainage pipeline and application thereof
The invention relates to the technical field of building materials, in particular to high-durability concrete for drainage pipelines and application thereof.The concrete is prepared from, by weight, 200-220 parts of cement, 90-100 parts of mineral admixture, 790-810 parts of sand, 470-490 parts of small stone, 710-730 parts of large stone, 25-35 parts of preservative, 145-155 parts of water and 6-6.5 parts of admixture; the mineral admixture is prepared by compounding mineral powder, phosphorus slag and lithium slag, and the preservative is prepared by compounding metakaolin, barium carbonate, calcium stearate and lithium carbonate. On the basis of the prior art, the mechanical property and the corrosion resistance of the concrete for the drainage pipeline are further improved, and the cost is not greatly increased.
本发明涉及建筑材料技术领域，具体涉及一种高耐久性排水管道用混凝土及其应用，按重量份计，该混凝土包括以下原料：水泥200‑220份，矿物掺合料90‑100份，砂790‑810份，小石470‑490份，大石710‑730份，防腐剂25‑35份，水145‑155份，外加剂6‑6.5份；所述矿物掺合料由矿粉、磷矿渣和锂矿渣复配，所述防腐剂由偏高岭土、碳酸钡、硬脂酸钙和碳酸锂复配，本发明中的矿物掺合料和防腐剂二者具有协同增效的作用，在现有技术的基础上进一步增加了排水管道用混凝土的力学性能和抗腐蚀性能，且不较大的增加成本。
