Concrete bearing insulating brick

Abstract

The invention relates to a concrete brick for bearing and insulation, which uses pumice, cement, swelling agent and gypsum as principal raw materials and is formed via mixing, stirring and pressing. The concrete brick for bearing and insulation is prepared and formed by the following variety of raw materials according to parts by weight: pumice powder of 50-70 parts, cement of 10-20 parts, gypsum of 5-15 parts and the swelling agent of 3-8 parts which are respectively measured, then adding water 5-15 parts and mixing and stirring intimately, and then performing extrusion shaping to form the product. The invention has the advantages of bearing, insulation, resisting compression, fireproofing, anti-vibration, crackle control, age-inhibiting, and non-toxicity, odorless and non-radiation.

Description

technical field [0001] The invention relates to a concrete load-bearing thermal insulation brick which takes pumice, cement, expansion agent and gypsum as main raw materials and is formed by mixing, stirring and extruding. Background technique [0002] At present, the polystyrene boards used in the market, the insulation boards made of polystyrene particles, smeared polymers and other external insulation materials, clay bricks and other wall materials all have problems of only heat preservation but no load-bearing, short service life or only load-bearing. The disadvantage of no heat preservation can not achieve the same lifespan as the building, and the above-mentioned materials also have the disadvantages of wasting cultivated land, polluting the environment, and labor intensity of workers during the manufacturing process. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned shortcomings and provide a concrete load-bear...
