The invention provides an energy-saving and environment-friendly swelling brick, which relates to a material for building. In order to overcome the deficiency caused by common clay red bricks which consumes a great land resources and energy, and has serious pollution, small size but heavy deadweight, poor heat insulation performance, and increase of the total construction cost; the swelling brick of the invention takes argillo-arenaceous rock as main material, which enters a high temperature rotary furnace to charge oxygen and pressure for swelling after crushing and screening, then a secondary heating is performed after producing the swelling body, finally the shape is formed by mechanical squeezing. The swelling body after shaped by squeezing also can be mixed with the cement, the fly ash and the concrete additive. After mechanically agitating and watering, the swelling body is conveyed to a silo for squeezing to form the swelling brick which is characterized by light weight, rigid body, heat insulation, and fire resistance, nontoxic and being durable, thus being an ideal energy-saving building brick.
