High-activity concrete admixture and method for producing high-activity concrete admixture by using stainless steel slag
The invention provides a high-activity concrete admixture and a method for producing the high-activity concrete admixture by using stainless steel slag. The method for producing the high-activity concrete admixture by using the stainless steel slag comprises the following steps: weighing according to the composition and proportion of the admixture, and uniformly mixing the four raw materials; wherein the admixture comprises the following components in parts by weight: 1-5 parts of desulfurized fly ash, 20-45 parts of stainless steel slag micro powder, 54-75 parts of manganese slag micro powder and 1-2 parts of a composite grinding aid; the specific surface area of the admixture micro powder is 400-500m < 2 >/Kg, and the content of metal iron is not higher than 1%. According to the invention, industrial wastes such as the stainless steel slag, the manganese slag and the desulfurized fly ash can be effectively utilized, the recycling of resources can be effectively realized, wastes are turned into wealth, the environment is protected, and meanwhile, good economic benefits can be generated.
本发明提供了一种高活性混凝土掺和料和一种利用不锈钢钢渣生产高活性混凝土掺和料方法。所述利用不锈钢钢渣生产高活性混凝土掺和料方法包括：按掺和料组成和配比进行称量，将上述四种原料混合均匀；其中，掺和料组成和配比为：每百份中，脱硫灰1～5份、不锈钢钢渣微粉20～45份、锰渣微粉54～75份和复合助磨剂1～2份；掺和料微粉比表面积为400～500m2/Kg，金属铁含量不高于1％。本发明可以有效的利用不锈钢钢渣、锰渣和脱硫灰等工业废弃物，可以有效的实现资源的回收利用，变废为宝和保护环境，同时还能产生良好的经济效益。
