发泡混凝土充填式多功能复合砌块(以下称充填式复合砌块),是以单排孔(或多排孔)混凝土空心砌块为基层,以混凝土实心片材为面层,基层与面层采用拉结件连接,其间通过填充超轻发泡混凝土形成保温层并发挥联接键作用。面层块材和基层片材均可采用普通混凝土、轻骨料混凝土、粉煤灰混凝土或建筑垃圾再生混凝土制备;为改善充填式复合砌块的装饰性,面层也可采用装饰混凝土。保温层采用在线填充工艺,并通过调整其厚度,确保充填式复合砌块的砌体传热系数满足不同使用地区建筑节能要求。充填式复合砌块是一种燃烧性能达到A1级的节能型墙体砌筑材料,符合我国墙体材料结构功能一体化的发展趋势,在我国夏热冬冷和寒冷地区具有良好的推广应用前景。
Foamed concrete filled multi-functional composite block (hereinafter referred to as filled composite block) is based on a single row of holes (or rows of holes) concrete hollow block as a base to concrete solid sheet for the surface layer, the grass-roots and surface Layers are connected by a pull knot, during which the insulation layer is formed by filling the ultra-light foamed concrete and functions as a coupling key. The surface block and the base layer sheet can be prepared by using ordinary concrete, lightweight aggregate concrete, fly ash concrete or construction waste recycled concrete; decorative concrete can also be used for the surface layer in order to improve the decorativeness of the filled composite block. The insulation layer adopts the online filling process, and by adjusting its thickness, the masonry heat transfer coefficient of the filled composite block can be ensured to meet the building energy saving requirements in different areas of use. Filling composite block is a kind of energy-saving wall masonry material with A1-level combustion performance, which is in line with the trend of integration of structure and function of wall materials in our country. It has a good prospect of popularization and application in cold summer and cold winter in China .
