Method for preparing recycled concrete based on activated water, and recycled concrete
The invention discloses a method for preparing recycled concrete based on activated water, and the recycled concrete. The recycled concrete comprises recycled concrete aggregate, recycled concrete cement, high-voltage electrostatic field activated water and natural sandstone. The preparation method of the recycled concrete comprises the following step: S1, preparing the recycled concrete aggregate, wherein waste concrete blocks are sorted by adopting a manual method, steel bars and wood are removed to form disintegrated concrete, then the disintegrated concrete is crushed by adopting a jaw crusher to form crushed concrete fragments, the crushed concrete fragments are conveyed into a hammer crusher by using a conveying belt and is then subjected to secondary crushing, and then the crushed concrete fragments are screened by using vibration screening equipment to obtain the recycled concrete aggregate. The activated water is adopted as a solvent, so the combination effect of all the components is improved; and the aggregate and the cement are prepared from waste concrete, coarse aggregate and fine aggregate replace a stone part in traditional concrete, the cement component is preparedby crushing the coarse aggregate and the fine aggregate into powder and mixing the obtained powder with slag powder, steel slag powder and desulfurized gypsum, so the utilization rate of the waste concrete is increased.
本发明公开了一种基于活化水制备再生混凝土的方法及再生混凝土，其再生混凝土，包括再生混凝土骨料、再生混凝土水泥、高压静电场活性水和天然砂石，其再生混凝土的制备方法，包括以下步骤，S1，再生混凝土骨料制备，采用人工法对废弃混凝土块进行分选，除去钢筋和木材，成为解体混凝土，再采用鄂式破碎机进行破碎形成破碎混凝土碎块，用传送带送入锤式破碎机中进行二级破碎，再用振动筛分设备筛分得到再生混凝土骨料。本发明溶剂采用活性水，提高各组分之间结合效果，骨料和水泥均通过废弃混凝土制备，粗细骨料替代传统混凝土中石料部分，水泥成分通过破碎成粉混合矿渣粉、钢渣粉和脱硫石膏制备，提高废弃混凝土利用率。
