Method for rapidly separating recycled coarse aggregate mortar
The invention discloses a method for rapidly separating recycled coarse aggregate mortar. The method comprises the following steps: heating recycled coarse aggregate, soaking the recycled coarse aggregate in cold water to gradually separate mortar from natural coarse aggregate, and repeatedly heating and soaking to finally remove the mortar. The time for separating the recycled coarse aggregate mortar is short, and the recycled coarse aggregate mortar can be removed within one day. The natural coarse aggregate and the mortar can be completely separated by heating and cooling the recycled aggregate for about 10 times. The operation is simple and feasible, and other redundant operations are not needed. Chemical reagents are not wasted, and secondary pollution is avoided after treatment. Some recycled coarse aggregate mortar needs to be separated by using acid to dissolve mortar wrapped outside recycled aggregate, and chemical pollution can be caused by excessive consumption and poor treatment of the acid.
本发明公开了一种快速分离再生粗骨料砂浆的方法，该方法通过将再生粗骨料加热后浸入冷水使砂浆逐渐与天然粗骨料分离，重复加热浸泡最终去除砂浆。本发明分离再生粗骨料砂浆的时间短，在一天内即可将再生粗骨料的砂浆去除。加热冷却再生骨料大约在10次左右就可以完全分离天然粗骨料和砂浆。操作简单可行，不需要其他多余的操作。不浪费化学试剂，处理后无二次污染。有的分离再生粗骨料砂浆需要用到酸来溶解再生骨料外包裹的砂浆，酸的消耗过多处理不好还会造成化学污染。
