The invention belongs to the technical field of building materials and provides a color brick produced from fly ash and a production method. The color brick produced from the fly ash is prepared from components in parts by weight as follows: 35-51 parts of modified fly ash, 8-14 parts of calcium sulfate, 3-7 parts of gravel, 6-9 parts of earth and stone powder, 5-10 parts of an acrylic emulsion, 15-23 parts of pigments, 2-5 parts of an early strength agent, 5-19 parts of an adhesive and 7-20 parts of water. The raw materials are fed into a forming mold and treated, and a brick body is formed; the brick body is subjected to steam curing for 8-9 h, and the color brick can be obtained. According to the color brick produced from the fly ash and the production method, the problem about fly ash recycling is solved, the preparation method of the color brick produced from the fly ash has the advantages that production period is shortened, sintering is not needed, heat energy is not required, time is saved, productivity is improved, cost is reduced, and more importantly, the problem of environmental pollution caused by the fly ash can be relieved; besides, the prepared color brick is lower in energy consumption, has no pollution to the environment and is light in weight and pollution-free, and a product is better in cracking resistance and toughness.
