摘　　要：建筑外墙是建筑物热量损耗的最关键部位,推行墙材革新,提高墙体保温隔热性能,成为我国建筑节能工作的重点之一。作为自保温墙体,页岩烧结多孔砖在农村建筑市场具有应用价值。农作物秸秆作为农村地区丰富的可再生资源,其资源化利用却存在一定的局限性。农作物秸秆因具有良好的保温隔热、成孔和燃烧性能,可用于改善自保温墙体的热工性能。将农作物秸秆作为成孔剂和内燃料,与页岩混合烧制成烧结多孔砖,并给出制备原理及工艺流程。农作物秸秆烧结多孔砖体现变废为宝、环保节能、减轻自重、节地减排的优势,在我国农村地区住宅建设过程中具有广阔的应用前景。As an important part of the energy consumption structure,building energy consumption is increasing in share of society total energy consumption.Exterior walls are the most critical parts of building heat loss,thus promoting wall material innovation and increasing wall insulation performance has become one of the focus of building energy efficiency in China.As self-thermal insulation wall,shalesintered perforated brick has applicable value in rural construction market.As abundant renewable resources in rural areas,there are some limitations in its resource utilization.Crop stalk has good insulating,pore-forming properties and combustibility,thus crop straw can be used to improve the thermal performance of thermal insulation wall.Using crop straw as the pore-forming agent and internal combustion agent,mixed with shale,porous brick is sintered and production principle,technological process of straw shale sintering perforated brick was given.Using crop straw sintered perforated brick has some advantages of turning waste into treasure,environmental protection and energy saving,reducing weight and saving emission reduction,which has broad application prospects in rural residential construction process in China.
