Ferrochrome slag for concrete aggregate and preparation method of ferrochrome slag
The invention belongs to the technical field of concrete modification and specifically relates to ferrochrome slag for concrete aggregate and a preparation method of ferrochrome slag. The ferrochromeslag for the concrete aggregate comprises the following components in parts by weight: 80-95 parts of ferrochrome slag, 5-10 parts of metakaolin and 8-15 parts of zeolite powder. Composite powder formed by the metakaolin and the zeolite powder is attached to the surface of the ferrochrome slag. Technical innovation is carried out from the perspectives of inhibiting chromium dissolution and solidifying dissolved chromium, so the ferrochrome slag can be applied to concrete and has industrial value.
本发明属于混凝土改性技术领域，具体涉及一种用于混凝土骨料的铬铁渣及其制备方法，按照重量份数计算，包括如下组分：铬铁渣80~95份，偏高岭土5~10份，沸石粉8~15份，其中，偏高岭土与所述沸石粉形成复合粉体附着在所述铬铁渣表面。本发明从抑制铬溶出和固化溶出铬的角度出发进行了技术创新，使得铬铁渣能够在混凝土中得到应用，具有产业价值。
