Treatment method of recycled aggregate, concrete containing recycled aggregate and preparation method of concrete
The invention relates to the field of environment-friendly concrete, in particular to a treatment method of recycled aggregate, concrete containing the recycled aggregate and a preparation method of the concrete. A treatment method of recycled aggregate comprises the following steps: step 1, crushing, screening and cleaning concrete waste to obtain pretreated recycled aggregate; 2, mixing 1-10% of nano silicon dioxide, 1-5% of styrene-acrylic emulsion and water to obtain a mixed solution; soaking the pretreated recycled aggregate in the mixed solution; after solid-liquid separation, the solid part is first recycled aggregate; 3, stearic acid and an organic solvent are mixed, and a 1-5 wt% stearic acid solution is obtained; soaking the first recycled aggregate in a stearic acid solution for 1-3 hours; after solid-liquid separation, the solid part is the recycled aggregate. The recycled aggregate provided by the invention is applied to concrete, not only is green and environment-friendly, but also can effectively overcome the problems of high water absorption and low performance of the traditional recycled aggregate, and has a good development prospect.
本申请涉及环保混凝土领域，更具体地说，它涉及再生骨料的处理方法及含再生骨料的混凝土及其制备方法。一种再生骨料的处理方法，包括以下步骤：步骤1：破碎、筛分、清洗混凝土废料，得到预处理再生骨料；步骤2：将1‑10%纳米二氧化硅、1‑5%苯丙乳液与水混合，得到混合溶液；将预处理再生骨料浸泡于混合溶液内；固液分离后，固体部分为第一再生骨料；步骤3：将硬脂酸与有机溶剂混合，得到1‑5wt%的硬脂酸溶液；将第一再生骨料浸泡在硬脂酸溶液中1‑3h；固液分离后，固体部分为再生骨料。本申请所提供的再生骨料应用在混凝土中，不仅绿色环保，而且能够有效克服传统再生骨料的吸水性高、性能低下问题，具有良好发展前景。
