Resumen
(EN)
The present invention discloses building waste treating and reusing process, which includes the following steps: classifying building wastes into waste concrete, waste stone material, waste ceramic, waste sintered brick and waste lime-sand brick; crushing separately into coarse grains and eliminating metal, timber and other impurity; milling into 5 mm below regenerated fine aggregate; sorting 0.15 mm below high quality fine aggregate and milling into regenerated fine powder material of 250-600 sq m/kg specific surface area; and preparing mortar, concrete, asphalt concrete and other building material with the regenerated fine aggregate and the regenerated fine powder.

本发明公开了一种建筑废弃物的处理及再生利用方法。该方法是将建筑废弃物中的废混凝土、废混凝土类墙体材料、废石材、废陶瓷、废烧结砖瓦和灰砂砖,先将其按种类进行分选;分别破碎到分米或厘米级粒度后,剔除金属、木材等杂质;再将其分别破碎或碾磨到小于5mm,形成再生细骨料;进一步将再生细骨料中小于0.15mm的颗粒分选出来,形成优质再生细骨料;分选出来的小于0.15mm的颗粒经进一步磨细后,制得比表面积为250m2/kg~600m2/kg的再生细粉料。本发明根据不同来源的再生细骨料和再生细粉料可根据需要单掺或复掺,能够制备砂浆、混凝土、沥青混合料、无机结合料稳定材料、墙体材料、水泥、矿物掺合料等建筑材料。
