| description | The invention relates to 3D printing recycled mortar based on super absorbent resin and a preparation method of the 3D printing recycled mortar. The recycled mortar is prepared from cement, fine aggregate, the super absorbent resin, a water-retaining agent, a retarder, a thickening agent, a water reducing agent and water. According to the invention, the super absorbent resin is used as a curing agent in the mortar to carry out water release compensation on the high water absorption rate of the reclaimed sand by utilizing the time-varying characteristic of water absorption and water release of the super absorbent resin, so that the super absorbent resin has better extrudability and constructability. The regenerated mortar prepared by the invention has better volume stability, effectively reduces product cracking caused by shrinkage, has a strength grade equivalent to that of natural sand, realizes effective utilization of regenerated sand in 3D printing concrete, and has double advantages of low carbon and sol |
