The invention relates to the technical field of concrete, and particularly discloses an activated water recycled concrete preparation method and recycled concrete. The preparation method of the activated water recycled concrete comprises the following steps: (1) activating industrial tap water by using electric field activation equipment to obtain activated water; mixing the activated water with Portland cement to obtain cement slurry, mixing the cement slurry with waste concrete particles, stirring to obtain slurry-coated particles, performing steam curing on the slurry-coated particles, and performing vibration screening to obtain slurry-coated recycled coarse aggregate; (2) mixing the fine aggregate, the slurry-coated recycled coarse aggregate, Portland cement, fly ash, industrial tap water and a polycarboxylate superplasticizer to obtain a concrete mixture; and (3) curing the concrete mixture in a mold, and removing the mold after curing to obtain the activated water recycled concrete. The crack resistance of the recycled concrete is improved, and the cracking risk of the recycled concrete is reduced.
本申请涉及混凝土技术领域，具体公开了一种活化水再生混凝土制备方法及再生混凝土。活化水再生混凝土制备方法包括以下步骤：（1）使用电场活化设备对工业自来水进行活化处理，得到活化水；将活化水和硅酸盐水泥混合，得到水泥浆，将水泥浆与废弃混凝土颗粒混合并进行搅拌，得到包浆颗粒，将包浆颗粒蒸汽养护后进行振动筛分，得到包浆再生粗骨料；（2）将细骨料、包浆再生粗骨料、硅酸盐水泥、粉煤灰、工业自来水、聚羧酸减水剂混合，得到混凝土拌和物；（3）对混凝土拌和物进行入模养护，养护结束后进行拆模，得到活化水再生混凝土。本申请提高了再生混凝土的抗裂性能，减小了再生混凝土开裂的风险。
