Concrete regeneration aggregate industrial mortar

The invention relates to an industrial mortar which adopts concrete recycled aggregate as the main filling raw material. The building solid wastes are classified and processed by regeneration treatment into concrete recycled aggregate whose grain size is less than or equal to 5 mm; the concrete recycled aggregate whose grain size is less than or equal to 5 mm, a cementing material, an excipient, an external additive and water, etc. are respectively measured, and then are mixed by a mixer to be made into a ready-mixed mortar or a dry mortar which can be used as the plastering mortar for the ground slab, the plastering mortar for the wall surface and the masonry mortar. As the porosity of the concrete recycled aggregate is high and the thermal performance is good, when the made industrial mortar is used as the plastering mortar for the ground slab and the wall surface, the industrial mortar is favorable for improving the heat preservation performance and the building energy saving level of the ground slab and t
