The invention provides an alkali-excited concrete for sewage pipelines and a preparation method thereof. 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, and 5 parts of fly ash. -10 parts, 40-50 parts of water, 35-45 parts of alkali activator, 0.25-0.5 part of admixture, 0.5-1 part of fiber, 100-150 parts of fine aggregate, 75-125 parts of coarse aggregate, through the present invention The combination of materials can significantly improve the impermeability and durability of concrete, so that the concrete itself has better resistance to sulfate corrosion. |
