Conductive mortar, preparation method thereof and auxiliary anode material
The invention relates to the technical field of constructional engineering protective materials, and provides conductive mortar, a preparation method thereof and an auxiliary anode material, and the conductive mortar comprises the following components in percentage by weight based on 100% of the total weight of the conductive mortar: 10-25% of cement, 0.04-3.6% of a carbon material, 58-75% of sand, 1.0-10% of fly ash, 1.0-10% of mineral powder and 9-14% of water. According to the conductive mortar provided by the invention, a macroscopic or microscopic conductive grid is constructed in the cement mortar through the carbon material, the fly ash and the mineral powder, a conductive path can be constructed together, and the resistivity of the conductive mortar is reduced. The coal ash and the mineral powder are cooperatively used, so that secondary hydration can be performed in the cement hydration process, pores of the conductive mortar or concrete are effectively filled with the coal ash and the mineral powder, invasion of chloride ions into the cement can be reduced, OH <-> consumption is reduced, and the auxiliary anode acidification resistance of the conductive mortar is improved.
本申请涉及建筑工程防护材料技术领域，提供了一种导电砂浆及其制备方法和辅助阳极材料，以导电砂浆的总重量为100％计，包括如下重量百分含量的组分：10～25％的水泥，0.04～3.6％的碳材料，58～75％的砂，1.0～10％的粉煤灰，1.0～10％的矿粉和9～14％的水。本申请提供的导电砂浆，通过碳材料、粉煤灰和矿粉在水泥砂浆内部构建宏观或微观导电网格，可以共同搭建导电通路，降低导电砂浆的电阻率。粉煤灰和矿粉的协同使用，可在水泥水化过程中进行二次水化，使粉煤灰和矿粉有效填充到导电砂浆或混凝土的孔隙中，可以减少氯离子向水泥内部侵入，从而减少OH﹣消耗，提升导电砂浆抵抗辅助阳极酸化能力。
