Energy-saving environment protection bulking brick

Abstract

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.

Description

technical field [0001] The invention relates to a building material, in particular to a building block brick. Background technique [0002] Sintered ordinary brick, commonly known as "red brick", also known as "solid clay brick", is a material widely used in house construction. Due to its simple production process, mature technology, convenient material acquisition, low cost, good heat insulation, Fire resistance and durability have been used in our country for thousands of years and are still used today. However, because traditional red bricks have caused great damage to land resources in the process of obtaining materials, and there are still high consumption and high pollution conditions in the firing process, the production of red bricks has seriously threatened land resources and the ecological environment. In June 2005, the General Office of the State Council issued the "Notice on Further Promoting the Renewal of Wall Materials and Promotion of Energy-Saving Buildings...
