Salt-freezing-resistant high-performance precast concrete curb and preparation method thereof
The invention relates to a salt-freezing-resistant high-performance precast concrete curb and a preparation method thereof, and solves the technical problem of poor salt freezing resistance of the existing precast concrete curb. The concrete curb is prepared from the following raw materials in parts by mass: 350-430 parts of cement, 730-810 parts of sand, 840-1020 parts of pebbles, 20-80 parts of fly ash, 30-80 parts of mineral powder, 12-18 parts of an additive, 140-210 parts of water, 0.6-0.9 parts of a GH-1 type anti-permeability agent and an emulsifier, and 0.4-1.0 part of a GH-2 type anti-permeability agent and an emulsifier. The invention also provides a preparation method of the concrete curb. The preparation method can be applied to the field of preparation of curbs.
