Alkali-activated concrete for sewage pipeline
The invention provides alkali-activated concrete for a sewage pipeline and a preparation method of the alkali-activated concrete, and the concrete material comprises the following raw materials in parts by weight: 45-75 parts of slag, 10-15 parts of silica fume, 6-12 parts of metakaolin, 5-10 parts of fly ash, 40-50 parts of water, 35-45 parts of an alkali activator, 0.25-0.5 part of an additive,0.5-1 part of fibers, 100-150 parts of fine aggregate and 75-125 parts of coarse aggregate. The anti-permeability and durability of the concrete can be remarkably improved, so that the concrete has relatively good sulfate corrosion resistance.
本发明提供一种用于污水管道的碱激发混凝土及其制备方法，混凝土材料包括以下重量份原料：矿渣45‑75份，硅灰10‑15份，偏高岭土6‑12份，粉煤灰5‑10份，水40‑50份，碱激发剂35‑45份，外加剂0.25‑0.5份，纤维0.5‑1份，细骨料100‑150份，粗骨料75‑125份，经本发明的材料组合，可显著改善混凝土的抗渗和耐久性，使混凝土自身具备较好对的抗硫酸盐侵蚀能力。
