More Information
Summary:The invention provides a green cement-based material used in a sulfate corrosion environment, and belongs to the technical field of cement-based building materials. Comprising the following raw materials in parts by weight: 40-60 parts of high belite sulphoaluminate cement clinker, 10-30 parts of coal-series metakaolin, 10-30 parts of CFB ash, 8-12 parts of styrene-butadiene latex, 1-3 parts of polypropylene fiber, 1-3 parts of a defoaming agent, 1-3 parts of an alkali activator and 1-3 parts of a water reducing agent. In a sulfate corrosion environment, the mass of the green cement-based grouting material is increased along with the increase of the age, SO4 < 2-> can enter a test block to participate in a reaction and produce a corresponding corrosion product, so that the material structure is more compact, and the mass of the test block is continuously increased; the problem that the compressive strength in a sulfate corrosion environment is continuously reduced due to poor sulfate corrosion resistance of a
