A 4-dimensional printing system and method for printing reinforced concrete may allow reinforced concrete elements to be printed freeform and/or fully automated without the need for formwork, molding, or labor. The printing system may include software and hardware systems. The software system may process 3D models of the reinforced concrete element desired into multiple layers. The software system may utilize the individual layer to control operation of the hardware system to print the desired reinforced concrete element layer-by-layer. The hardware system may provide a concrete nozzle, a reinforcement material nozzle, as well as dispensing mechanisms for printing the materials at the desired locations and/or at desired times for the individual layer being printed. The hardware system may also include motion control mechanism(s) that allow the position of the nozzles to be moved side-to-side, up and down, and towards or away relative to the element being printed as desired during the printing process.

The present disclosure relates to a visible light-catalyzed translucent concrete, and a preparation method and use thereof. The preparation method includes: extracting an iron oxide from a copper slag, mixing the iron oxide with TiO.sub.2 to obtain a photocatalyst, and then mixing the photocatalyst with an additive to obtain a photocatalytic slurry; preparing a concrete slurry using the copper slag after iron extraction as an aggregate; and pouring the photocatalytic slurry, the concrete slurry, and the photocatalytic slurry in sequence into a mold pre-laid with an optical fiber, to obtain the visible light-catalyzed translucent concrete. In the visible light-catalyzed translucent concrete, iron in the copper slag is used as a part of raw materials of the photocatalyst, and the copper slag after iron extraction is used as an aggregate to replace natural sand and gravel. This solves environmental pollutions caused by the copper slag and realizes resource utilization.
