The invention discloses a construction waste recycled aggregate water milled colorful paving brick and a preparation method thereof, and belongs to the field of building materials. The colorful paving brick is prepared by the following raw materials in parts by weight: 200-260 parts of fine aggregates, 60-80 parts of rough aggregates, 5-10 parts of aggregate modifier, 30-80 parts of nanometer silicon dioxide, 50-70 parts of polyamide, 0.3-0.5 parts of water reducing agent, 100-140 parts of cement and 40-70 parts of water. The product adopts construction waste recycled aggregates as the main raw material, thus being naturally multicolored, reducing processes and expenses for doping stones and pigments, beautifying the environment, reducing cost and saving natural resources. Meanwhile, the invention also provides a preparation method of the water milled colorful paving brick, the preparation method is simple in process, the prepared product is high in permeability performance and mechanical performance, and strong in ultraviolet ray and thermal radiation absorbing ability, and reduces urban heat island effect in the summer.
