| abstract |
The invention relates to a high-performance geopolymer concrete and a preparation method thereof. The disclosed high performance geopolymer concrete is prepared from fly ash, slag micropowder, sodium hydroxide, water glass, water reducing agent, fine aggregate, coarse aggregate, steel fiber and polypropylene fiber. The disclosed preparation method is to add and mix the components of the formula in a reasonable order, wherein the polypropylene fibers are added twice during the mixing process, and the steel fibers are laid in layers during the concrete pouring process. The invention has a significant effect on improving the brittleness of the geopolymer concrete, increasing its ductility, and saving the amount of fiber at the same time. |
