Cementing material taking steel slag as raw material and preparation method thereof
The invention discloses a cementing material taking steel slag as a raw material and a preparation method thereof, the cementing material comprises the following components in parts by weight: 100 parts of a powder material, 0.5-1 part of dimethyl carbonate, 0.05-0.15 part of a retarder, 0.2-0.5 part of a water reducing agent and 38-50 parts of water, the powder material is prepared from the following components in parts by weight: 30-45 parts of ground steel slag powder, 20-30 parts of granulated blast furnace slag powder, 5-10 parts of calcium aluminate, 15-20 parts of gypsum and 5-10 parts of coal ash. According to the method, large-scale application of the steel slag in the field of building materials is promoted according to the solid waste resource utilization requirement, a large amount of superfine steel slag powder formed by grinding industrial solid waste steel slag is utilized, and the utilization rate of industrial waste is effectively increased. Meanwhile, compared with a common cementing material, the cementing material has the characteristics of greenness, environmental protection, energy conservation, emission reduction, carbon reduction, low economic cost, short setting time, high early strength, stable later strength increase, good volume stability and the like.
本发明公开了一种以钢渣为原材料的胶凝材料及其制备方法，按质量份计，胶凝材料由以下组分组成：粉体材料100份、碳酸二甲酯0.5~1份、缓凝剂0.05~0.15份、减水剂0.2~0.5份、水38~50份，其中，以重量份数计，粉体材料由以下组分组成：磨细钢渣粉30~45份、粒化高炉矿渣粉20~30份、铝酸钙5~10份、石膏15~20份、粉煤灰5~10份。本发明围绕固体废弃资源化利用需求，促进钢渣在建筑材料领域的大规模应用且大量利用工业固体废弃物钢渣磨细而成的超细钢渣粉，有效提高工业垃圾的利用率。同时与普通胶凝材料相比，该胶凝材料具有绿色环保、节能减排降碳、经济成本低，凝结时间短，早期强度高，后期强度增长稳定、体积稳定性好等特点。
