Modified rubber particle lightweight ultra-high performance concrete and preparation method thereof
The invention discloses modified rubber particle lightweight ultra-high performance concrete and a preparation method thereof. The concrete is prepared from cement, fly ash microbeads, silica fume, pottery sand, rubber particles, copper-plated steel fibers, waterborne epoxy resin, a water-retaining shrinkage-reducing internal curing agent, a water reducing agent and water as main raw materials, wherein the rubber particles are prepared by crushing waste tires and then modifying the crushed waste tires. The modified rubber particle lightweight ultra-high performance concrete has the advantagesof light weight, high strength, high impact toughness, abrasion resistance and good volume stability, and has practical application value.
本发明公开了一种改性橡胶颗粒轻质超高性能混凝土及其制备方法，它以水泥、粉煤灰微珠、硅灰、陶砂、橡胶颗粒、镀铜钢纤维、水性环氧树脂、保水减缩内养护剂、减水剂和水为主要原料制备而成，其中，橡胶颗粒采用废旧轮胎破碎后经过改性制成。本发明所述改性橡胶颗粒轻质超高性能混凝土具有轻质高强、抗冲击韧性高、耐磨蚀、体积稳定性好的优点，具有实际应用价值。
