The invention belongs to the technical field of concrete, and particularly relates to a high-strength concrete pipe pile which comprises the following components in parts by weight: 40-60 parts of cement, 30-50 parts of a mineral admixture, 90-130 parts of sand, 200-240 parts of gravel, 5-10 parts of a water reducing agent and 20-40 parts of water. According to the high-strength concrete pipe pile, a part of cement is replaced with the mineral admixture, the mineral admixture is high in activity and can generate a pozzolanic reaction and the like, calcium silicate hydrate is generated, the strength is improved, meanwhile, the particle size of the mineral admixture is smaller than that of the cement, an effective filling effect can be achieved, the compactness of the concrete is improved, and the service life of the concrete pipe pile is prolonged. And the strength and the anti-seepage capability of the concrete are further improved, so that the concrete pipe pile with higher strength and better anti-seepage capability is helped to be obtained.
本申请属于混凝土技术领域，具体涉及一种高强度混凝土管桩，包括如下重量份的各组分：水泥40‑60份、矿物掺料30‑50份、砂90‑130份、碎石200‑240份、减水剂5‑10份、水20‑40份。本申请的高强度混凝土管桩，通过用矿物掺料代替一部分水泥，由于矿物掺料的活性较高，可以发生火山灰反应等，生成水化硅酸钙，提高强度，同时，矿物掺料的粒度比水泥更小，可以起到有效的填充作用，提高混凝土的密实性，进一步提高混凝土强度、抗渗能力，从而帮助获得强度更高，抗渗能力更好的混凝土管桩。
