Concrete for light anti-corrosion electric pole and preparation method thereof
The invention provides concrete for a light anti-corrosion electric pole. The concrete is prepared from the following raw materials in parts by weight: 130 to 150 parts of micro-silica fume, 480 to 500 parts of ordinary Portland cement, 70 to 80 parts of limestone powder, 7.5 to 8.5 parts of efficient water reducing agent, 20 to 30 parts of basalt fiber, 20 to 30 parts of glass fiber, 680 to 720 parts of washed river sand, 1100 to 1150 parts of gravel and 110 to 130 parts of water. The invention further provides a preparation method of the concrete for the light anti-corrosion electric pole, and the concrete has extremely low permeability, high environmental medium erosion resistance and good durability, has high tensile strength and bending strength, good toughness and ductility, and can be used for preparing the light anti-corrosion electric pole. Good freezing resistance, carbonization resistance, hydrochloric acid and sulfuric acid corrosion resistance, chemical solution corrosion resistance and wear resistance are achieved; the limestone powder is doped into the concrete, so that the viscosity of a concrete mixture can be obviously reduced, and distribution can be easily carried out in the manufacturing process of the electric pole; the wall thickness of the electric pole prepared by the invention can be thinner than that of an electric pole prepared by ordinary Portland cement, so that the manufacturing cost and the transportation cost of the electric pole are greatly reduced.
本发明提供一种用于轻型防腐电杆的混凝土，包括如下重量份数的原料：微硅灰130‑150，普通硅酸盐水泥480‑500，石灰石粉70‑80，高效减水剂7.5‑8.5,玄武岩纤维20‑30,玻璃纤维20‑30,水洗河砂680‑720,碎石1100‑1150,水110‑130；本发明还提供一种用于轻型防腐电杆的混凝土制备方法，本发明的混凝土具有极低的渗透性、较高的抗环境介质侵蚀能力和良好的耐久性，具有较高的抗拉强度和抗弯强度、良好的韧性和延性，还具有良好的抗冻性、抗碳化性、抗盐酸硫酸侵蚀、抗化学溶液侵蚀及耐磨性；本发明在混凝土中掺入石灰石粉，可以明显降低混凝土拌合物黏度，让电杆在制作过程中的可以轻松进行布料；采用本发明制备的电杆可以比用普通硅酸盐水泥制备的电杆壁厚更薄，大大降低了电杆的制造成本和运输成本。
