Cement-based conductive composite material and preparation method thereof
The invention provides a cement-based conductive composite material, and relates to the technical field of cement materials. The cement-based conductive composite material comprises the following components by weight: 80-100 parts of cement; 110-140 parts of fly ash; 80-100 parts of silica fume; 70-120 parts of water; 1-5 parts of a water reducing agent; 10 to 15 parts of rubber powder; 1-5 partsof steel fibers; 1-3 parts of carbon fiber; 1-3 parts of polyvinyl alcohol fiber; and 30-50 parts of ferrite. The invention also provides a preparation method of the cement-based conductive compositematerial, which comprises the following steps of: uniformly mixing the cement, the fly ash, the silica fume and the rubber powder; adding the water, the steel fibers, the carbon fibers, the polyvinylalcohol fibers, the ferrite and the water reducing agent, and stirring for 5-10 minutes; pouring the mixture into a mold, and vibrating for 1-3 minutes; pressurizing to remove bubbles, strickling thesurface, and maintaining for 24-36 hours; and carrying out demolding maintenance for 28-30 days. The material disclosed by the invention has a relatively strong electromagnetic wave absorption function in a wide frequency range, and has relatively good compressive strength.
本发明提供了一种水泥基导电复合材料，涉及水泥材料技术领域，按重量份计包括以下组分：水泥80～100份；粉煤灰110～140份；硅灰80～100份；水70～120份；减水剂1～5份；橡胶粉10～15份；钢纤维1～5份；碳纤维1～3份；聚乙烯醇纤维1～3份；铁氧体30～50份，还提供了一种水泥基导电复合材料的制备方法，包括将水泥、粉煤灰、硅灰、橡胶粉混合均匀；加入水、钢纤维、碳纤维、聚乙烯醇纤维、铁氧体和减水剂，搅拌5～10min；倒入模具中，振动1～3min；加压排除气泡，刮平表面养护24～36h；脱模养护28～30d。本发明的材料在宽频率范围内具有较强的电磁波吸收功能，并具有较好地抗压强度。
