Cement-based material of conductive heating concrete and preparation method of cement-based material
The invention discloses a cement-based material of conductive heating concrete and a preparation method of the cement-based material, and relates to the technical field of inorganic non-metallic materials. The cement-based material comprises the following components in percentage by mass: 75%-90% of high-iron sulphoaluminate cement clinker; 0%-12% of gypsum; 5%-15% of mineral waste residue; 0.1%-1.0% of carbon fibers; 0.2%-5.0% of anthracite coal; wherein the mineral waste residue is one or a combination of more of copper slag, sulfuric acid slag and electrolytic manganese slag. According to the invention, the high-performance cementing material is compounded with the high-stability low-cost waste residue mineral admixture and the carbon fibers with good conductivity, and the dispersion performance of the fibers is improved by mechanically activating the mineral admixture and adopting a simple dispersion mode, so that the cement cementing material with good conductivity is formed.
本发明公开了一种导电发热混凝土的水泥基材料及其制备方法，涉及无机非金属材料技术领域。该水泥基材料包括以下按质量百分比计的组分：高铁硫铝酸盐水泥熟料：75%~90%；石膏：0%~12%；矿物废渣：5%~15%；碳纤维：0.1%~1.0%；无烟煤：0.2%~5.0%；其中，所述矿物废渣为铜矿渣、硫酸渣和电解锰渣中的一种或多种的组合。本发明通过利用高性能的胶凝材料复合高稳定性低成本的废渣矿物外掺料及导电性能良好的碳纤维，采用机械活化矿物外掺料及简单的分散方式提纤维的分散性能，形成具有良好导电性能的水泥胶凝材料。
