Environment-friendly recycled concrete and preparation method thereof
The invention relates to the technical field of concrete, and particularly discloses environment-friendly recycled concrete and a preparation method thereof. The environment-friendly recycled concreteis prepared from the following components in parts by weight: 1000-1500 parts of concrete recycled aggregate; 200-300 parts of cement; 200-300 parts of water; 5-10 parts of a water reducing agent; 5-7 parts of an air entraining agent; 5-7 parts of isoprene; and 500-600 parts of a filling material; wherein the concrete recycled aggregate comprises recycled fine aggregate and recycled coarse aggregate in a weight ratio of 1:(1-1.5). The preparation method comprises the following steps: mixing the concrete recycled aggregate and the filler to obtain a mixture A; adding cement, a water reducing agent, an air entraining agent and isoprene into water, and stirring to obtain a mixture B; adding the mixture B into the mixture A, and stirring and mixing all the components. According to the environment-friendly recycled concrete, waste concrete is used as a raw material, energy conservation and environmental protection are achieved, meanwhile, the production cost is reduced, and sustainable development is promoted.
本申请涉及混凝土技术领域，具体公开了一种环保再生混凝土及其制备方法。一种环保再生混凝土包括如下重量份数的组分：混凝土再生骨料1000‑1500份；水泥200‑300份；水200‑300份；减水剂5‑10份；引气剂5‑7份；异戊二烯5‑7份；填料500‑600份；混凝土再生骨料包括重量比为1：（1‑1.5）的再生细骨料和再生粗骨料。其制备方法包括以下步骤：将混凝土再生骨料、填料混合得到混合物A；将水泥、减水剂、引气剂、异戊二烯加入水中搅拌得到混合物B；将混合物B加入到混合物A中搅拌混合。本申请的环保再生混凝土，使用废弃混凝土为原料，节能环保，同时降低生产成本，促进可持续发展。
