High-toughness cement-based hybrid synthetic fiber composite material and preparation method thereof
The invention discloses a high-toughness cement-based composite material and a preparation method thereof. The invention relates to the field of constructional engineering materials, which comprises the following components: Portland cement, silica fume, metakaolin, sand, large stones, small stones, water, a water reducing agent, a defoaming agent, synthetic coarse polypropylene fibers (CPP), coarse denier polyvinyl alcohol fibers (PVA) and polyacrylonitrile fibers, and the Portland cement, the silica fume, the metakaolin and fly ash form a cementing material. The formula comprises the following components in parts by mass: 800 parts of cement, 70 parts of silica fume, 70 parts of fly ash, 60 parts of metakaolin, 1880 parts of sand, 2300 parts of large stone, 1250 parts of small stone, 410 parts of water, 0.5% of water reducing agent and 0.1% of defoaming agent. The fibers comprise, by volume, 1% of synthetic coarse polypropylene fibers (CPP), 0.3% of coarse denier polyvinyl alcohol fibers (PVA) and 0.1% of fine fibers (polyacrylonitrile fibers). The cement-based composite material prepared according to the mixing ratio provided by the invention has the advantages of good toughness and high strength.
