Autoclaved aerated concrete double-hard-face building block and manufacturing and construction method thereof

Bis hardfacing autoclaved aerated concrete block manufacturing and construction and method of building technology are energy-saving. The double hardfacing autoclaved aerated concrete block, including three sub-step of pouring the same layer region naturally formed, characterized in that: said block of three hard surface layer region were region (2), the base layer region ( 1), hard surface region (2); layer region (1) having a density of 200KG / M3 ~ 400KG / M3 of autoclaved aerated concrete, hard surface region (2) having a density of distilled 600KG / M3 ~ 1200KG / M3 of pressure aerated concrete, reinforced masonry with Rachel (3), Rachel reinforcement (3) the entire block is inserted from the end portion. This kind of autoclaved aerated concrete block dual hard surface that meets the energy requirements but also meet the requirements of flexural impact, its production method enriched and developed the manufacturing process of autoclaved aerated concrete, has a distinct sense of technological progress.
