Corrosion-resistant concrete pole and preparation method thereof
The invention discloses a corrosion-resistant concrete pole and a preparation method thereof. According to the concrete pole, the superfine slag powder and the fly ash are used as superfine admixtures and are mixed with the coarse aggregate and the fine aggregate in a graded mode, so that internal pores of the prepared concrete pole are effectively reduced, the compactness of a concrete layer is improved, and the prepared pole is not prone to external corrosion in the using process; the preservative is one or a combination of sodium nitrite, calcium nitrite, sodium benzoate, sodium fluosilicate, barium carbonate, barium nitrate and lithium carbonate, and the air entraining agent is one of lignosulfonate, a rosin hot extract and Sanjiao saponin. The service environment of the telegraph pole is further enhanced, the telegraph pole can be suitable for being used in different environments, the corrosion resistance of the whole telegraph pole is improved, and the impact toughness of the concrete telegraph pole is improved by adding reinforcing fibers into the concrete layer, and the reinforcing fibers have good tensile strength and ductility.
本发明公开了一种耐腐蚀的混凝土电杆及其制备方法。本发明中，将矿渣微粉和粉煤灰作为超细掺和料，通过与粗骨料和细骨料的分级混配，使制得的混凝土电杆内部孔隙有效减少，提升混凝土层的致密程度，使得制得的电杆在使用过程中，不会轻易受到外界的腐蚀，防腐剂为亚硝酸钠、亚硝酸钙、苯甲酸钠、氟硅酸钠、碳酸钡、硝酸钡、碳酸锂中的一种或其组合，同时添加引气剂，为木质素磺酸盐、松香热取物、三贴皂苷中一种。进一步使得该电线杆的受用环境得到了增强，使得其可以适合不同环境中使用，增加了整体电杆的耐腐蚀性能，通过在混凝土层中加入增强纤维，增强纤维具有很好的抗拉强度和延伸率，提升混凝土电杆的冲击韧性。
