Durable high-strength concrete pipe pile concrete and application
The invention provides durable high-strength concrete tubular pile concrete and application, and the durable high-strength concrete tubular pile concrete is prepared from the following raw materials in parts by weight: 75-85 parts of Portland cement, 15-25 parts of admixture, 150-220 parts of fine aggregate, 260-400 parts of coarse aggregate, 1-1.5 parts of water reducing agent, 1.5-2 parts of early strength agent, 8-10 parts of binder and 23-30 parts of water, the binder is composed of nonionic water-based blocked isocyanate and water-soluble silicone oil according to the mass ratio of (0.6-0.8): 1. According to the invention, the water-soluble silicone oil and the non-ionic water-based blocked isocyanate are used as binders, the non-ionic water-based blocked isocyanate is de-blocked at a high temperature, and an isocyanate group reacts with hydroxyl on the water-soluble silicone oil to form bonding particles capable of enhancing the cohesiveness of concrete; the toughness of the pipe pile concrete can be improved, cracks are reduced, the strength is improved, ion permeation can be prevented, and the durability of the concrete is improved.
本发明提供了一种耐久高强混凝土管桩混凝土及应用，包括如下重量份的原料：75‑85份硅酸盐水泥、15‑25份掺合料、150‑220份细骨料、260‑400份粗骨料、1‑1.5份减水剂、1.5‑2份早强剂、8‑10份粘结剂、23‑30份水，所述粘结剂由非离子型水性封闭异氰酸酯与水溶性硅油按质量比为0.6‑0.8:1组成。本发明以水溶性硅油、非离子型水性封闭异氰酸酯为粘结剂，利用非离子型水性封闭异氰酸酯在高温解封闭，异氰酸酯基会和水溶性硅油上的羟基发生反应形成可增强混凝土粘结性的粘结粒子，不仅能改善管桩混凝土的韧性、减少裂缝、提高强度，还可阻止离子渗透、提高混凝土的耐久性。
