High-performance cement-based composite material and preparation method thereof
The invention discloses a high-performance cement-based composite material and a preparation method thereof, and belongs to the technical field of building materials, the composite material comprises the following raw materials: water, quartz sand, fly ash, a water reducing agent, nano SiO2, cement and polyvinyl alcohol fiber; the preparation method comprises the following steps: mixing cement, fly ash and quartz sand to obtain mortar; mixing nano SiO2 with a water reducing agent, adding part of water, stirring, adding the obtained dispersion liquid into the mortar, stirring, adding the rest water, stirring, and adding polyvinyl alcohol fiber to obtain the cement-based composite material. According to the cement-based composite material disclosed by the invention, the nano SiO2 and the polyvinyl alcohol fiber in a certain proportion are simultaneously doped into the cement-based composite material, so that the performance of the cement-based composite material under the coupling action of damp and hot salts is remarkably enhanced, and the application of the cement-based composite material in hydraulic structures and ocean engineering is more facilitated.
本发明公开了一种高性能水泥基复合材料及其制备方法，属于建筑材料技术领域，所述复合材料原料包括：水、石英砂、粉煤灰、减水剂、纳米SiO2、水泥及聚乙烯醇纤维；所述制备方法包括：将水泥、粉煤灰和石英砂混合得到砂浆；将纳米SiO2与减水剂混合后加入部分水、搅拌，将得到的分散液加入所述砂浆中并搅拌，之后加入剩余的水，搅拌后加入聚乙烯醇纤维即得所述水泥基复合材料；本发明通过在水泥基复合材料中同时掺入一定比例的纳米SiO2和聚乙烯醇纤维，显著增强了水泥基复合材料在湿热盐耦合作用下的性能，更有利于水泥基复合材料在水工结构物及海洋工程中的应用。
