This invention discloses a color-difference-free, uniformly luminescent concrete and its preparation method. Addressing the problems of easy hydrolysis and sedimentation of luminescent powder in alkaline cement, and the significant reduction in luminescence efficiency due to physical coating, the invention uses white silicate cement, refined quartz sand, uncoated rare-earth-doped strontium aluminate luminescent powder, and rutile titanium dioxide as the base mixed raw materials. During preparation, a multi-component liquid phase containing sodium polyacrylate, sodium gluconate, sodium aluminate, strontium nitrate, polyvinyl alcohol, and sodium tetraborate is added to the slurry in a stepwise manner and stirred.
