Abstract
The production process and application of large composite external wall panels (composite panels for short) are introduced in this paper. Composite panels with both load bearing and thermal insulation were formed by pouring normal concrete (NC) and ceramsite foamed concrete (CFC) continuously according to particular technological requirements, which made two layers into a seamless whole. The layers of NC and CFC are for load bearing and thermal insulation respectively. The composite panels were manufactured in the scale of industrial production, and applied to several energy saving prefabricated buildings successively, instead of polystyrene sandwich composite panels (sandwich panel for short) as external wall panels. There are several obvious advantages of the composite panel over the sandwich panel or outer benzoic board. Firstly, it solved the problems of durability of polystyrene and the complex production process of the sandwich pane, the production process of the external wall was thus greatly simplified. In addition, the fire risk was much reduced.
Highlights
Nowadays efficient construction and green building are regarded as the development goals of the building industry in China, and a perfect combination of prefabricated construction with an energy saving system is considered an effective way to achieve the goal
The composite panels were made of normal concrete (NC) and ceramsite foamed concrete (CFC) with a continuous pouring process to achieve a seamless interface of two layers
The performance of the thermal insulation of the composite panels could be changed by adjusting density and thickness of the CFC layer to satisfy the requirements of practical engineering
Summary
Nowadays efficient construction and green building are regarded as the development goals of the building industry in China, and a perfect combination of prefabricated construction with an energy saving system is considered an effective way to achieve the goal. A concrete sandwich slab with a core of EPS or XPS as insulation layer prefabricated in the concrete product plant gets over some defects of outer benzoic board system, it is still a complex process and durability problem as well. The composite panels were made of normal concrete (NC) and ceramsite foamed concrete (CFC) with a continuous pouring process to achieve a seamless interface of two layers. The former is for load bearing, and the latter for thermal insulation respectively. The composite panel has good thermal insulation due to a network of closed fine pores of the CFC layer, and its outer surface has architectural decoration as well as a water proof effect. Other decorative facade to imitate stone texture, wood grain and brickwork and so on are available
