Modified phosphorus slag powder, preparation method and application of modified phosphorus slag powder in concrete in large mixing amount
The invention relates to modified phosphorus slag powder, a preparation method and application of the modified phosphorus slag powder in large mixing amount in concrete, and the modified phosphorus slag powder is prepared from the following raw materials in parts by mass: 100 parts of phosphorus slag, 0.001-2 parts of C-S-H nano crystal nucleus and 0.005-0.1 part of alcohol amine organic matter; according to the invention, the phosphorus slag powder is combined with the C-S-H nanocrystal nucleus and the alcohol amine organic matter in a grinding manner, so that the phosphorus slag powder can be used as a mineral admixture in concrete in a large mixing amount; c-S-H nanocrystal nucleuses in the modified phosphorus slag powder can play a role in grinding aiding and also have an early strength effect, and the C-S-H nanocrystal nucleuses can also adsorb soluble fluorine and phosphorus in the phosphorus slag powder, so that the negative effect of the soluble fluorine and phosphorus on delaying the setting time of concrete is eliminated.
本发明涉及一种改性磷渣粉和制备方法及其在混凝土中大掺量的应用，按质量份数计，包括以下原料：100份磷渣、0.001～2份C‑S‑H纳米晶核以及0.005～0.1份醇胺类有机物；本发明将磷渣粉通过研磨的方式与C‑S‑H纳米晶核和醇胺类有机物结合起来，使得其作为矿物掺合料在混凝土中可大掺量使用；改性磷渣粉中的C‑S‑H纳米晶核既可起到助磨作用，又具有早强效果，且C‑S‑H纳米晶核还可吸附磷渣粉中的可溶性的氟和磷，消除了可溶性氟和磷延缓混凝土凝结时间的负面作用。
