Preparation method of high-toughness cement-based composite material
The invention discloses a preparation method of a high-toughness cement-based material, which comprises the following steps of: pretreating straw plant fibers, and doping a cement base with the pretreated straw plant fibers. The modified cement-based material is obtained by mixing straw plant fibers, cement, sand, a polycarboxylic acid water reducing agent and water, wherein relative to 1000 kg of cement, the use amount of the plant fibers is 0-200 kg, the use amount of the sand is 2700-3200 kg, and the use amount of the water is 500-800 kg. According to the invention, the plant fibers are modified, and the composite material of the plant fibers treated by a sodium hydroxide solution has good compressive strength and breaking strength, and also has good plasticity, toughness, crack resistance and tensile resistance. The fiber-reinforced cement-based material is prepared by taking agricultural waste straw plants as a main raw material, and the method is beneficial to reducing the manufacturing cost, saving resources and solving the pollution of waste to the environment, so that the environment is protected.
本发明公开了一种利用高韧性水泥基材料的制备方法，需要对秸秆植物纤维进行预处理，再掺加到水泥基里。本发明的改性水泥基材料是由秸秆植物纤维、水泥、砂、聚羧酸减水剂、水混合得到：其中，相对于1000kg水泥、所述的植物纤维的用量为0～200kg，砂子的用量为2700～3200kg，所述的水为500～800kg。本发明经过对植物纤维改性，通过氢氧化钠溶液处理过的植物纤维的复合材料，有较好的抗压强度、抗折强度，同时具备良好的塑性和韧性、以及抗裂和抗拉伸性能；本发明采用农业废弃物的秸秆植物作为主要原料制备一种纤维增强水泥基材料，该方法有助于降低制作成本、节约资源，解决废料对环境的污染，从而保护环境。
