Zusammenfassung:	The invention belongs to the field of building materials, and provides a recycled aggregate old mortar weak layer removing method which comprises the following steps: crushing concrete to obtain recycled aggregate; soaking the recycled aggregate in an isopropanol solution until the recycled aggregate is saturated, and then taking out the recycled aggregate to obtain initial recycled aggregate; putting the initial recycled aggregate into an absolute ethyl alcohol solution, soaking until saturation, and then taking out to obtain intermediate recycled aggregate; soaking the intermediate recycled aggregate in a mixed solution of isopropanol and absolute ethyl alcohol until the intermediate recycled aggregate is saturated, and then taking out the intermediate recycled aggregate to obtain treated recycled aggregate; taking the three soaking processes as a cycle, and periodically and repeatedly soaking until deformation cracks appear on the interface of the old mortar and the recycled aggregate to obtain the recycle
