The invention discloses a method for making bricks by using construction wastes. The bricks are characterized by comprising the following raw materials: 30-57 parts of crushed aggregates of construction wastes of which the metal particles are removed and the diameter is small than 14mm, 20-40 parts of coal gangue particles, 10-15 parts of phosphate slag with the particle diameter being less than 1mm, 8-15 parts of cement, 0.6-0.8 part of quick lime, 3-18 parts of pulverized fuel ash, 0.01-0.025 part of a hydroxyl silicon sealed curing agent, 8-12 parts of water and 0.1-0.2 part of sodium silicate. The crushed aggregates of construction wastes can be dismantled materials of old buildings or wastes of novel buildings, and an anti-freezing agent or an anti-freezing chlorine salt can be added into the raw materials. The method has the advantages that the proportioning is simple, the energy is renewable, the environment is protected, and the wastes are utilized.
