Zusammenfassung:	The invention belongs to the technical field of building materials, and particularly relates to a 3D printing low-carbon optimized deformation concrete slab and a preparation process thereof. The concrete slab comprises a compression layer, a transition layer and a tension layer from top to bottom. The compression layer is formed by printing alkali-activated concrete; the transition layer is formed by printing low-carbon green concrete; the tensile layer is formed by printing high-ductility concrete with ECC (high-ductility cement-based composite material) as a base body and an FRP grating as a reinforcement body. By combining the 3D printing concrete technology, the components of the plate material are changed in space, the performance advantages of various materials are brought into full play, the bearing capacity and ductility of the 3D printing concrete plate are improved, and the practicability of the 3D printing concrete plate is improved; meanwhile, a green cementing material is introduced, the cement
