Preparation method for producing gravel aggregate from construction waste
The invention discloses a preparation method for producing gravel aggregate from construction waste. The preparation method comprises the following steps: selecting recycled coarse aggregate; a step of microbial mineralization deposition reinforcement of the recycled coarse aggregate; according to the scheme, physical strengthening, microbial mineralization and chemical strengthening are combined, mortar on the surfaces of particles is reduced through physical strengthening, then microcracks are filled with microbial mineralization, and larger cracks are filled with chemical slurry, so that the performance of the recycled coarse aggregate is improved; and large-scale resource utilization of the construction waste is realized.
本发明公开了一种建筑垃圾生产砂石骨料的制备方法，包括以下步骤：再生粗骨料的选择；再生粗骨料微生物矿化沉积强化步骤；再生粗骨料化学浆液强化步骤，本方案将物理强化、微生物矿化及化学强化三者结合，以物理强化降低颗粒表面的砂浆，之后以微生物矿化填充微裂缝，以化学浆液填充稍大的裂缝，从而提升再生粗骨料的性能，实现建筑垃圾的大规模资源化利用。
