specific Embodiment approach 1

[0027] Specific Embodiment 1: The expanded block brick mud-sand rock of this embodiment is used as raw material, obtained according to the following method: a, using mud-sand rock as raw material, crushed and screened with a particle size of 1-2 mm; b, then entering the high-temperature rotary furnace for oxygenation Pressurize for puffing, wherein the furnace temperature is controlled at 1200-1400°C, the pressure is 3-8MPa, and the humidity is adjusted to 0.5-0.8%. After the puffed body is produced, the secondary heating is carried out, and the temperature is controlled at 1400-1600°C; c. Finally, it is mechanically extruded to obtain expanded block bricks.

specific Embodiment approach 2

[0028] Specific embodiment two: the expanded block brick mud-sand rock of the present embodiment is as raw material, obtains according to the following method: a, take mud-sand rock as raw material, crushing and screening particle size is 1.5mm; Extrusion is carried out under pressure, wherein the furnace temperature is controlled at 1400°C, the pressure is at 5MPa, and the humidity is adjusted to 0.6%. After the puffed body is produced, the second heating is carried out, and the temperature is controlled at 1500°C; c. Finally, mechanical extrusion molding is obtained to obtain 240mm× 240mm×115mm expanded block bricks with a density of 1000Kg / m 3 , the compressive strength in the non-load-bearing state is 5Mpa, the water absorption rate is 13%, the thermal conductivity is 0.35W / m·k, the mass loss rate of 50 freeze-thaw cycles is 4%, and the strength loss rate is 15%.

specific Embodiment approach 3

[0029] Specific implementation mode three: the expanded block brick mud-sand rock of this embodiment is the main raw material, and is obtained according to the following method: a, with mud-sand rock as raw material, crushed and screened with a particle size of 1 to 2 mm; b, then entering into a high-temperature rotary furnace Oxygen is pressurized for puffing, wherein the furnace temperature is controlled at 1200-1400°C, the pressure is 3-8MPa, and the humidity is adjusted to 0.5-0.8%. After the puffed body is produced, the second heating is carried out, and the temperature is controlled at 1400-1600°C to obtain Expanded body; c. The expanded body is mechanically crushed into granules, and the particle size is controlled between 2mm to 5mm, and then mixed with cement, fly ash, and concrete additives. The weight percentage of each raw material is: expanded body 30-50%, cement 15% 25%, 20-40% of fly ash, 5-15% of concrete additives, after mechanical stirring and adding water, tr...

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...
