The invention relates to a high-strength superfine admixture concrete pole and a preparation method thereof.The concrete pole comprises a steel reinforcement framework and a concrete layer wrapping the steel reinforcement framework, and the concrete layer comprises, by weight, 80-140 parts of water; 400 to 460 parts of cement; 1000 to 1200 parts of coarse aggregate; 600 to 650 parts of fine aggregate; 40 to 160 parts of superfine slag powder; 40 to 100 parts of fly ash; 1-10 parts of an additive; the thickness of the concrete layer ranges from 25 mm to 35 mm. 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 grading manner, so that internal pores of the prepared concrete pole are effectively reduced, the compactness of a concrete layer is improved, and the bending resistance, the crack resistance and the impact resistance of the concrete pole are further enhanced; the concrete layer of the concrete pole can have high strength performance under the condition that the thickness is small.
本申请涉及一种高强度超细掺和料混凝土电杆及其制备方法，混凝土电杆包括钢筋骨架和包覆所述钢筋骨架的混凝土层，所述混凝土层包括以下重量份的原材料：水80~140份；水泥400~460份；粗骨料1000~1200份；细骨料600~650份；矿渣微粉40~160份；粉煤灰40~100份；外加剂1~10份；所述混凝土层的厚度为25~35㎜。本申请将矿渣微粉和粉煤灰作为超细掺和料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，混凝土层的致密程度，进而使混凝土电杆的抗弯、抗裂和抗冲击性能得到进一步的增强，混凝土电杆的混凝土层在较薄的厚度下即可具有较高的强度性能。
