Manufacturing method of lightweight luminous starry sky concrete slab

The invention discloses a manufacturing method of a lightweight luminous starry sky concrete slab. The method specifically comprises the following steps: preparing a concrete mixture according to component requirements; cement, silica fume, pottery sand and medium sand are mixed to obtain a mixture A, and polypropylene fibers are scattered into the mixture A to obtain a mixture B; adding fluorescent powder and resin luminous sand into the mixture B to obtain a mixture C, and adding water and a water reducing agent into the mixture C to obtain a luminous concrete material; a film coating agent is brushed on the steel formwork, Chinese art paper is laid on the surface, brushed with the film coating agent, of the steel formwork, and a retarder is sprayed on the Chinese art paper; a concrete material is poured into the steel formwork and vibrated, the surface of the poured luminous concrete is scraped to be flat, and then the diluted retarder solution is evenly sprayed to the surface of the poured luminous concre
