Organic silicon slag and magnesium slag composite reinforced recycled aggregate and preparation method thereof
The invention belongs to the field of comprehensive recycling of solid wastes, and particularly relates to organic silicon slag and magnesium slag composite reinforced recycled aggregate and a preparation method thereof. The preparation method comprises the following steps: S1, mixing organic silicon slag, water and an alcohol amine grinding aid, and performing wet grinding to obtain organic silicon slag slurry; s2, magnesium slag and an alcohol amine grinding aid are mixed and subjected to dry grinding, and magnesium slag micro powder is obtained; s3, uniformly mixing the magnesium slag micro powder, the organic silicon slag slurry and water to obtain turbid liquid; s4, the recycled aggregate is soaked in water, surface impurities are removed through ultrasonic cleaning, then the recycled aggregate is taken out and soaked in the turbid liquid obtained in the step S3, stirring is conducted for 24-48 h at the speed of 100-300 r/h, natural drying is conducted after soaking is completed, and the organic silicon slag and magnesium slag composite reinforced recycled aggregate is obtained. According to the invention, comprehensive application of three solid wastes is realized, pollution of solid wastes to environments such as land, air and the like is reduced, a technical path for enhancing the recycled aggregate is provided, and good economic and social benefits are achieved.
本发明属于固体废弃物综合再利用领域，具体是涉及一种有机硅渣与镁渣复合增强再生骨料及其制备方法。其制备方法包括以下步骤：S1：将有机硅渣、水、醇胺类助磨剂混合湿磨，得到有机硅渣泥浆；S2：将镁渣、醇胺类助磨剂混合干磨，得到镁渣微粉；S3：将镁渣微粉、有机硅渣泥浆、水混合均匀，得到悬浊液；S4：将再生骨料浸泡于水中，超声清洗去除表面杂质，然后取出再浸泡于步骤S3得到的悬浊液中，100～300r/h搅拌24～48h，浸泡完成后自然干燥，即得一种机硅渣与镁渣复合增强再生骨料。本发明实现了三种固废的综合应用，减少了固体废弃物对土地、空气等环境的污染，提供了一种增强再生骨料的技术路径，具备良好的经济社会效益。
