Preparation method of andesite recycled aggregate concrete
The invention relates to a preparation method of andesite recycled aggregate concrete, which comprises the following steps: 1) crushing waste concrete by using a jaw crusher, and removing impurities in the waste concrete; (2) the crushed waste concrete obtained in the step (1) passes through a magnetic separator, and scrap iron contained in the original waste concrete is removed; (3) screening the waste concrete obtained in the step (2) by a screening machine, and crushing the waste concrete with larger particle size again by repeating the step (1); (4) the screened waste concrete is poured into water and stirred, impurities floating on the water surface are removed, and then the waste concrete is taken out and dried; (5) carrying out modification treatment on the waste concrete obtained in the step (4); and 6) grinding the waste concrete modified in the step 5) to obtain the finished product recycled aggregate. The invention relates to the technical field of recycled concrete. According to the invention, the water absorption of the gravel is reduced, and the strength of the gravel is improved, so that the quality of the andesite recycled concrete is improved.
本发明涉及一种安山岩再生骨料混凝土的制备方法，1)用颚式破碎机将废弃混凝土破碎，并将其中的杂物剔除；2)将步骤1)中得到破碎后的废弃混凝土通过磁选机，将原有废弃混凝土中含有的废铁去除；3)将步骤2)中得到的废弃混凝土经筛分机进行筛分，并将粒径较大的废弃混凝土重复步骤1)再次粉碎；4)将筛分后的废弃混凝土倒入水中并搅拌，清理水面上漂浮的杂物，然后取出废弃混凝土并烘干；5)对步骤4)得到的废弃混凝土进行改性处理；6)将步骤5)中改性处理的废弃混凝土进行研磨得到成品再生骨料。本发明涉及再生混凝土的技术领域。本发明降低了碎石的吸水性，并提高碎石的强度，进而提高了安山岩再生混凝土的质量。
