Concrete pipe pile and preparation method thereof
The invention belongs to the technical field of concrete. The invention provides a concrete pipe pile and a preparation method thereof. The concrete pipe pile is prepared from 280 to 320 parts of Portland cement, 600 to 700 parts of sea sand, 90 to 100 parts of mineral powder, 45 to 50 parts of silica fume, 1200 to 1300 parts of gravel, 5 to 10 parts of a water reducing agent, 5 to 20 parts of rubber powder and 100 to 120 parts of water. The bending strength, compressive strength and cracking resistance of the prepared concrete pipe pile are obviously superior to those of a concrete pipe pile prepared through high-pressure steam curing, and the concrete pipe pile is high in safety performance and low in reaction energy consumption; by adding the rubber powder, the anti-cracking performance and the fluidity of the concrete pipe pile are improved; by using mineral powder, silica fume and rubber powder, the use amount of cement is reduced, and the anti-cracking performance and durability of the concrete pipe pile are improved; the waste rubber is recycled, so that the environment is protected, and secondary recycling of resources is realized.
本发明属于混凝土技术领域。本发明提供了一种混凝土管桩及其制备方法。混凝土管桩由280～320份硅酸盐水泥、600～700份海砂、90～100份矿粉、45～50份硅灰、1200～1300份碎石、5～10份减水剂、5～20份橡胶粉和100～120份水制备而成。本发明制得的混凝土管桩的抗弯强度、抗压强度和抗开裂性能均明显优于通过高压蒸汽养护制得的混凝土管桩，并且，安全性能高，反应能耗低；通过加入橡胶粉，提高了混凝土管桩的抗开裂性能和流动性；通过使用矿粉、硅灰和橡胶粉降低了水泥的用量，提高了混凝土管桩的抗开裂性能和耐久性；通过对废弃橡胶进行再生利用，保护了环境，实现了资源的二次循环使用。
