Steel slag modification method
The invention relates to a steel slag modification method. The steel slag modification method comprises the following steps: providing clean steel slag and nano silicon dioxide dispersion liquid; the steel slag is soaked in the nano silicon dioxide dispersion liquid; and obtaining the soaked steel slag, and drying to obtain the modified steel slag. According to the steel slag modification method provided by the embodiment of the invention, the steel slag is soaked in the nano silicon dioxide dispersion liquid, so that surface pores of the steel slag are filled with nano silicon dioxide with extremely small particle size, meanwhile, compact calcium silicate gel is generated to wrap the surface of the steel slag, the surface can be roughened, and the overall strength of the steel slag is improved. The steel slag soaking expansion rate is reduced only through the technical means of soaking the steel slag with the nano silicon dioxide dispersion liquid, and the method has the advantages of being environmentally friendly, low in energy consumption, simple in process and good in modification effect.
本申请涉及一种钢渣改性方法，所述钢渣改性方法包括如下步骤：提供洁净的钢渣和纳米二氧化硅分散液；将所述钢渣在所述纳米二氧化硅分散液中浸泡；获取浸泡完成的钢渣，干燥后得到改性钢渣。本申请实施例提供的钢渣改性方法，通过将钢渣在纳米二氧化硅分散液中浸泡，实现了粒径极小的纳米二氧化硅填充了钢渣的表面孔隙，同时生成致密的硅酸钙凝胶包裹在钢渣表面，还能使表面粗糙，提高了钢渣的整体强度。本申请仅通过使用纳米二氧化硅分散液浸泡钢渣的技术手段实现了降低钢渣浸水膨胀率，具有对环境友好、耗能低、工艺简单、改性效果好的优点。
