High-toughness cement-based composite material as well as preparation method and application thereof
The invention relates to a high-toughness cement-based composite material as well as a preparation method and application thereof, and the cement-based composite material comprises the following components in parts by weight: 200-300 parts of cement; 300 to 400 parts of a mineral admixture; 300 to 500 parts of machine-made sand; 10-20 parts of an organic fiber material; 0.2 to 1.0 part of a water reducing agent; 2-35 parts of a modified material; the modified material is one or a combination of more of a polymer, a silane coupling agent and hydrated silicon dioxide. The high-toughness cement-based composite material prepared by taking the cement and the mineral admixture as gel materials, adopting the machine-made sand as aggregate to completely replace quartz sand, adding a specific modified material to improve a microstructure in the material and assisting with an organic fiber material has excellent compressive strength and bending strength, also has excellent bonding performance, and can be used for preparing the high-toughness cement-based composite material. An organic whole can be formed with the existing building structure, and the anti-seismic and anti-cracking performance of the existing building is remarkably improved.
本发明涉及一种高韧性水泥基复合材料及其制备方法和应用，按重量份计，所述水泥基复合材料包括以下组分：水泥200～300份；矿物掺合料300～400份；机制砂300～500份；有机纤维材料10～20份；减水剂0.2～1.0份；改性材料2～35份；所述改性材料为聚合物、硅烷偶联剂和水合二氧化硅中的一种或几种的组合。本发明以水泥和矿物掺合料为凝胶材料，采用机制砂作为集料完全取代石英砂，添加特定改性材料改善材料内部的细观结构，并辅以有机纤维材料制备的高韧性水泥基复合材料，具有优异的抗压强度和抗弯强度，同时具有优异的粘结性能，能够与既有建筑结构形成有机整体，显著提高既有建筑的抗震和抗开裂性能。
