Environment-friendly micro-expansion high-ductility cement-based composite material and preparation method thereof
The invention belongs to the technical field of civil engineering materials, and particularly discloses an environment-friendly micro-expansion high-ductility cement-based composite material and a preparation method thereof. Portland cement, fly ash, blast furnace slag, water, quartz sand, gypsum, an early strength agent, a thickening agent, an expanding agent, a water reducing agent, a defoaming agent and polyvinyl alcohol fibers are compounded, liquid raw materials of water, the water reducing agent and the defoaming agent are added into solid raw materials, and finally, the polyvinyl alcohol fibers are added and uniformly mixed. The environment-friendly micro-expansion high-ductility cement-based composite material is prepared. The cement-based composite material prepared by the invention has micro-expansion performance, can inhibit early-stage shrinkage cracks of the material, and can enhance the ductility of the material at the same time.
本发明属于土木工程材料技术领域，具体公开了一种环保微膨胀高延性水泥基复合材料及其制备方法。本发明通过硅酸盐水泥、粉煤灰、高炉矿渣、水、石英砂、石膏、早强剂、增稠剂、膨胀剂、减水剂、消泡剂、聚乙烯醇纤维复配，将水、减水剂、消泡剂液体原料加入到固体原料中，最后再添加聚乙烯醇纤维混合均匀，制得一种环保微膨胀高延性水泥基复合材料。本发明制备的水泥基复合材料具有微膨胀性能，能够抑制材料的早期收缩裂缝，同时能够加强材料的延性。
