Building solid waste recycled concrete admixture
The invention relates to the technical field of building solid waste recycled concrete, in particular to a building solid waste recycled concrete admixture, which comprises the following steps of S1, building solid waste crushing pretreatment, S2, sorting: magnetic sorting and sundry sorting, S3, crushing, S4, flushing and screening: screening the metal reinforcing steel bars, the recycled micro powder, the recycled aggregate and the high-quality recycled sand powder, S5, ultrafine grinding of the recycled fine aggregate or sand powder, and S6, chemical strengthening and physical strengthening of the admixture. The concrete fragments are subjected to building solid waste crushing pretreatment, sorting, crushing, washing and screening, recycled fine aggregate or sand powder superfine grinding and chemical strengthening and physical strengthening of the admixture, the high-quality recycled aggregate with good grading and low impurity content can be obtained through the production mode, and by adjusting a screen, products with different particle sizes and different gradations can be obtained so as to meet various requirements.
本发明涉及建筑固废再生混凝土技术领域，尤其为一种建筑固废再生混凝土掺合料，包括以下步骤：S1，建筑固废破碎预处理；S2，分选：磁性分选和杂物分选；S3，破碎；S4，冲洗筛分：筛分金属钢筋、再生微粉、再生骨料和高品质再生砂粉；S5，再生细骨料或砂粉超细粉磨；S6，掺合料的化学强化和物理强化，通过将混凝土碎块经过建筑固废破碎预处理、分选、破碎、冲洗筛分、再生细骨料或砂粉超细粉磨、掺合料的化学强化和物理强化，这种生产方式可得到级配良好、含杂质少的高质再生骨料，通过调整筛网，还可以得到不同粒径、不同级配的产品，以满足各种需求。
