Construction waste treatment process
The invention provides a construction waste treatment process, which comprises the following steps: S1, obtaining recycled aggregate; S2, heating the recycled aggregate to 300 DEG C to 500 DEG C; andS3, grinding and screening the heated recycled aggregate to obtain the high-quality aggregate. According to the invention, recycled aggregate is heated to 300-500 DEG C to dehydrate and embrittle mortar wrapping natural aggregate, and then the mortar wrapping the natural aggregate is removed through grinding, so that the strength, the impermeability and other properties of the recycled aggregate are greatly improved so as to widen the application range of the recycled aggregate.
本公开提供了一种建筑垃圾处理工艺，包括：S1.获取再生骨料；S2.将再生骨料加热至300℃～500℃；S3.将加热后的再生骨料研磨并筛分得到高品质骨料。本公开通过将再生骨料加热至300℃～500℃，使包裹在天然骨料外的砂浆脱水脆化，然后再经过研磨去除包裹在天然骨料外的砂浆，从而极大地提高了再生骨料强度、抗渗性等性能，进而拓宽再生骨料的使用范围。
