Composite steel slag activator, modified steel slag material containing composite steel slag activator and preparation method thereof
The invention discloses a composite steel slag activator which is prepared from the following components in parts by mass: 2-8 parts of calcium sulfate, 0.08-0.8 part of sodium carbonate, 0.08-0.8 part of citric acid, 2-5 parts of polyhydric alcohol, 0.23-1.1 parts of polyhydric alcohol amine, 0.01-0.03 part of a silane coupling agent and 0.02-0.05 part of metal fluoride. The invention further discloses a modified steel slag material containing the composite steel slag activator and a preparation method thereof. The activator provided by the invention can excite the activity of the steel slag, the waste steel slag is used as a useful material to be continuously applied to production and life, the utilization rate of the waste material is improved, and circular economy is realized. When a modified steel slag material containing the activator is mixed with cement according to the mixing amount of 3: 7, the 28d compressive strength can be improved to 86%.
本发明公开了一种复合钢渣激发剂，其由以下组分按质量份制备而成：硫酸钙2‑8份，碳酸钠0.08‑0.8份，柠檬酸0.08‑0.8份，多元醇2‑5份，多元醇胺0.23‑1.1份，硅烷偶联剂0.01‑0.03份，金属氟化物0.02‑0.05份。本发明还公开了一种含有该复合钢渣激发剂的改性钢渣材料及其制备方法。本发明提供的激发剂能够激发钢渣的活性，将废弃钢渣作为有用的材料继续应用在生产生活中，提高废弃材料的利用率，实现循环经济。含有该激发剂的改性钢渣材料当与水泥按照3：7掺量进行混合时，28d抗压强度可提高到86％。
