Steam-curing-free energy-saving mineral admixture for concrete pipe pile and preparation method of steam-curing-free energy-saving mineral admixture
The invention relates to the technical field of concrete, in particular to a steam-curing-free energy-saving mineral admixture for a concrete pipe pile and a preparation method of the steam-curing-free energy-saving mineral admixture. The concrete comprises the following raw materials in parts by weight: 20-56 parts of an iron-containing tailing powder-silicon powder compound, 17-35 parts of modified coal gangue, 5-23 parts of diatomite, 3-8 parts of superfine slag powder, 2-10 parts of basalt fibers, 3-5 parts of polypropylene fibers, 3-8 parts of carbon nanofibers, 2-15 parts of an activating agent and 0.5-0.8 part of a grinding aid. The prepared admixture can be used as a tubular pile concrete admixture, the steps of steam curing and autoclaving of tubular pile concrete are omitted, the preparation steps are simple, and the effects of energy conservation and emission reduction can be achieved while the production cost is reduced.
本申请涉及混凝土技术领域，更具体地说，它涉及一种混凝土管桩用免蒸养节能矿物掺合料及其制备方法。按重量份数包括如下原料：含铁尾矿粉－硅粉复合物20‑56份，改性煤矸石17‑35份，硅藻土5‑23份，矿渣微粉3‑8份，玄武岩纤维2‑10份，聚丙烯纤维3‑5份，碳纳米纤维3‑8份，活化剂2‑15份，助磨剂0.5‑0.8份。制得的掺合料可用作管桩混凝土掺合料，免去管桩混凝土蒸养和蒸压步骤，制备步骤简单，降低生产成本的同时可以达到节能减排的效果。
