Concrete based on polymer/montmorillonite nano composite material and preparation method thereof

The invention provides concrete based on a polymer/montmorillonite nano composite material and a preparation method of the concrete. The concrete comprises the following components in parts by mass: 260-350 parts of cement, 465-510 parts of quartz sand, 140-180 parts of fly ash, 90-130 parts of a phenolic resin/montmorillonite nano-composite, 13-17 parts of a tackifier, 3-6 parts of a water reducing agent and 170-230 parts of water. By introducing the phenolic resin/montmorillonite nano-composite into a concrete system, the prepared concrete has very good high temperature resistance, compressive strength and impact and wear resistance. 本发明提供一种基于聚合物/蒙脱石纳米复合材料的混凝土及其制备方法，按照质量份数计，包括水泥260～350份、石英砂465～510份、粉煤灰140～180份、酚醛树脂/蒙脱石纳米复合物90～130份、增粘剂13～17份、减水剂3～6份、水170～230份。通过在混凝土体系中引入酚醛树脂/蒙脱石纳米复合物，制得的混凝土具有很好的耐高温、抗压强度以及抗冲磨性能。
