Construction solid waste refined treatment process
The invention discloses a construction solid waste refined treatment process. The process comprises the following steps of pretreatment, sorting treatment, primary crushing treatment, screening, primary screening of construction solid waste with the particle size of 0-100mm, primary manual sorting of other parts, secondary crushing to enable the particle size to be basically kept at 100-150mm, and secondary manual sorting; direct taking of the part with the particle size of 0-65 mm as garden soil or filling soil; color sorting of construction solid waste with the particle size of 65-95 mm, and achieving separation of more than 90% of bricks and concrete; and sequential treatment of selected bricks and concrete, direct combined grinding of the bricks with the particle size of 0-10 mm to prepare a high-activity mineral admixture, crushing of bricks with the particle size of 20 mm or above to prepare a curing material, after treatment of construction solid waste with the particle size of 95 mm or above, enabling the strength of particles with the particle size of 20 mm or above to be higher, and treatment to obtain high-strength and high-performance recycled aggregate with the particle size of 0-15 mm. According to the method, the construction solid waste is fully utilized, the product value of the construction solid waste is realized, and the ratio of recycled concrete aggregate particles after the solid waste is crushed is increased.
本发明公开了一种建筑固废精品化处理工艺，包括以下步骤：预处理，分选处理，一级破碎处理，筛分，0‑100mm粒径建筑固废进入一级筛分，其他部分进行一级人工分拣、二级破碎使粒径基本保持在100‑150mm，然后进行二级人工分拣；粒径0‑65mm的部分直接作为园林土或者填充土；粒径65‑95mm建筑固废进行色彩分选，实现砖和混凝土90％以上的分离；选出的砖和混凝土分别依次进行处理，粒径0‑10mm的砖直接进行联合粉磨，制备高活性矿物掺合料，粒径20mm以上的砖通过破碎制备养护材料，粒径95mm以上建筑固废处理后，粒径20mm以上的颗粒强度较高，进行处理得到粒径0‑15mm的高强高性能再生骨料；本发明实现建筑固废的充分利用，实现建筑固废产品价值，提高固废破碎后再生混凝土骨料颗粒的占比率。
