Preparation and application of novel improved composite steel slag exciting agent
The invention relates to the technical field of building materials, in particular to preparation and application of a novel improved composite steel slag excitant, and the novel improved composite steel slag excitant comprises a composite steel slag excitant, 0.5-1 part of polyol amine, 4-6 parts of polyol, 1-2 parts of sodium sulfate, 2-3 parts of calcined gypsum, 0.6-2.4 parts of sodium peroxide and 0.1-0.8 part of tartaric acid. Mixing according to the proportion, mechanically stirring at room temperature for 10 minutes, and then putting the mixture and the steel slag into a ball mill to be uniformly mixed to obtain a modified steel slag material; according to the GB/T17671-1999 test standard, 30% of the modified steel slag material and 70% of ordinary Portland cement are mixed; maintaining for 28 days in a water sample environment at the temperature of 25 DEG C, measuring the compressive strength, observing the pore distribution of the cross section and measuring the dry density of the batch of materials, the mixed exciting agent used in the invention can solve the problem of waste of a large amount of steel slag in industry, reduce CO2 emission, reduce environmental pollution, improve the sound insulation and heat insulation problems in the aspect of cement building materials, and improve the comprehensive performance of the cement building materials. And the market prospect is wide.
本发明涉及建筑材料技术领域，尤其涉及一种新型改良复合钢渣激发剂的制备与应用，包括有复合钢渣激发剂，多元醇胺0.5－1份，多元醇4‑6份，硫酸钠1－2份，烧石膏2－3份，过氧化钠0.6－2.4份，酒石酸0.1－0.8份。按照如上的配比混合在室温下机械搅拌10min，之后与钢渣一同放入球磨机里混合均匀得到改性后的钢渣材料；按照GB/T17671‑1999测试标准，将30％的改性钢渣材料和70％的普通硅酸盐水泥混合；在25℃的水样环境下养护28天，测其抗压强度，同时，观察截面的气孔分布和测定这批材料的干密度，本发明使用的混合激发剂能够解决工业上大量钢渣的废弃问题，降低CO2排放，减少环境污染，同时能够完善水泥建材方面的隔音隔热问题，具有广阔的市场前景。
