High-strength prestressed concrete pipe pile prepared from tungsten tailings and preparation method
The invention discloses a high-strength prestressed concrete pipe pile prepared from tungsten tailings, and belongs to the technical field of building material preparation, and the pipe pile per meter comprises the following raw materials by mass: 13.99%-46.63% of tungsten tailings, 35.96%-36.56% of cement, 7.05%-7.25% of silica fume, 0.00%-35.06% of sand, 1.95%-1.96% of an additive, 3.86%-4.00% of steel fiber, and the balance of water. According to the high-strength prestressed concrete pipe pile prepared from the tungsten tailings, the tungsten tailings are added in the preparation process, the purpose of preparing the high-strength prestressed concrete pipe pile prepared from the tungsten tailings is mainly achieved, the tungsten tailings are used for replacing part of raw materials of concrete, the occupied area of stacked tungsten tailings is reduced, and the high-strength prestressed concrete pipe pile prepared from the tungsten tailings is prepared.
本发明公开了一种钨尾矿制备的高强度预应力混凝土管桩，属于建筑材料制备技术领域，每米管桩的原料质量为：钨尾矿13.99％‑46.63％,水泥35.96％‑36.56％，硅灰7.05％‑7.25％，砂子0.00％‑35.06％，外加剂1.95％‑1.96％,钢纤维3.86％‑4.00％，余量为水。本发明一种钨尾矿制备的高强度预应力混凝土管桩，在制备过程中添加了钨尾矿，主要解决一种可综合利用的钨尾矿资源，利用钨尾矿代替混凝土部分原料，减少钨尾渣堆放占地，制备一种钨尾矿制备的高强度预应力混凝土管桩。
