Recycled fine aggregate concrete and preparation method thereof
The invention relates to the field of concrete, and particularly discloses recycled fine aggregate concrete and a preparation method thereof.The recycled fine aggregate concrete is prepared from, by weight, a cementing material, recycled fine aggregate, recycled coarse aggregate, water and an additive, natural aggregate does not need to be added into the prepared recycled fine aggregate concrete, cost is saved, and the recycled fine aggregate concrete can be recycled. The repeated utilization rate of the solid wastes can be improved; the preparation method of the recycled fine aggregate concrete comprises the following steps: S1, mixing and stirring cement, water, an additive and recycled coarse aggregate to obtain an intermediate mixture; s2, adding the admixture and the recycled fine aggregate into the intermediate mixture, and mixing and stirring to obtain a target product. The preparation method of the regenerated fine aggregate concrete is simple and convenient, the interaction force of all the raw materials in the concrete can be improved, all the raw materials give full play to the effect, and the regenerated fine aggregate concrete has good performance.
本申请涉及混凝土领域，具体公开了一种再生细石混凝土及其制备方法，再生细石混凝土包括以下按重量份计的原料：胶凝材料、再生细骨料、再生粗骨料、水和外加剂，本申请制得的再生细石混凝土中不需要添加天然骨料，既有助于节约成本，又有助于提高固体废弃物的重复利用率；本申请中再生细石混凝土的制备方法包括以下步骤，S1.将水泥、水、外加剂和再生粗骨料混合搅拌，得中间混合物；S2.向中间混合物中加入掺合料和再生细骨料后混合搅拌，得目标产物。本申请再生细石混凝土的制备方法简单便捷，且有助于提高混凝土中各原料的相互作用力，使各原料充分发挥作用，使再生细石混凝土具有较好的性能。
