UHPC thin-wall electric pole and preparation method thereof
The invention discloses a UHPC (Ultra High Performance Concrete) thin-wall electric pole and a preparation method thereof. Concrete adopted by the thin-wall electric pole comprises the following components in parts by weight: 500 to 550 parts of cement, 70 to 80 parts of silica fume, 140 to 160 parts of mineral powder, 55 to 65 parts of steel fiber, 7 to 8 parts of additive, 380 to 420 parts of machine-made sand, 550 to 650 parts of water-washed sand, 550 to 650 parts of coarse aggregate and 140 to 160 parts of water. According to the concrete pole prepared according to the formula, the machine-made sand and the water-washed sand are matched with the steel fiber and the coarse aggregate, the strength of the pole can be greatly improved, the cost is lower, the performance is better, the wall thickness can reach 30 mm, the weight is lighter, and transportation is convenient.
本发明公开了一种UHPC薄壁电杆及其制备方法，该薄壁电杆所采用混凝土包括水泥、硅灰、矿粉、钢纤维、外加剂、机制砂、水洗砂、粗骨料和水，各个成分重量份比为：水泥500‑550、硅灰70‑80、矿粉140‑160、钢纤维55‑65、外加剂7‑8、机制砂380‑420、水洗砂550‑650、粗骨料550‑650和水140‑160。本发明的配方制备的混凝土电杆，采用机制砂和水洗砂配合钢纤维和粗骨料，能够大大提高电杆的强度，成本更低，性能更好，壁厚能够做到30mm，重量更轻，便于运输。
