Method for manufacturing earth brick

Brick is the most traditional masonry material, which is divided into sintered brick (mainly clay brick) and non-sintered brick (lime sand brick, fly ash brick, etc. ), commonly known as bricks. Clay brick is made of clay (including shale, coal gangue and other powders) as the main raw material, which is processed, shaped, dried and roasted by mud. During the Spring and Autumn Period and the Warring States Period, China successively created square bricks and long bricks. During the Qin and Han dynasties, brick-making technology, production scale, quality and fancy varieties all developed significantly, and the world called it "Qinzhuan Hanwa".

Mixing rice straw and fiber mesh into the mud of brick, and using rice straw fiber and fiber mesh fiber to improve the viscosity of mud, sand and red soil can be intertwined. At the same time, the natural ecological performance of the building is improved by using the biomass characteristic that straw does not contain any harmful elements to human body.

The chaff has good sound insulation, heat insulation, heat preservation and corrosion resistance; In practice, it can be seen from the unearthed ancient tombs that a bag of "bran" was placed on the skull for more than 1000 years; It can be proved that adding chaff can improve the strong acid and alkali resistance of adobe.

Bricks can be made into rectangular standard bricks (a× b× c = 240×110× 54 mm) and other blocks. After testing, adobe brick shows that in the dead of night, the conversation next door can't be heard, and the attenuation decibel reaches more than 92%, and the sound insulation effect is good; It can bear the force per square centimeter 1 1- 15 kg, and its strength is strong enough; In winter, the outdoor temperature is MINUS 5 degrees, and the indoor temperature can reach about 5 degrees above zero, without heating; In summer, it is 30 degrees above zero outdoors, and it can reach about 20 degrees indoors without refrigeration. It is really warm in winter and cool in summer. The bulk density of this product is about 50% of that of clay brick.
