The establishment of the compilation group of the association's standard "Low thermal conductivity and low water absorption Composite Insulation Board" and the first working meeting were held in the way of network meeting on July 30, 2020. 24 representatives from China Concrete and Cement Products Association, China Architectural Design and Research Institute Co., LTD., China University of Geosciences and other institutions attended the meeting.

Participants listened to the report on the preliminary investigation and preparation of the standard, and fully exchanged the technical indicators and production application of the current low thermal conductivity and low water absorption composite insulation board products, and clarified the division of labor and standard preparation progress of the participating units, and Opinions and suggestions were put forward on key points such as the structure of the main chapters of the standard, key technical indicators, and test methods.

Low thermal conductivity and low water absorption composite insulation board improved the performance of foamed cement board to 50% solid Based on the waste content, the thermal conductivity and volumetric water absorption are reduced, thereby further broadening the application range of foamed cement boards in external insulation systems by using of hot-press foaming, pore wall-bubble dual control, inorganic-organic composite, fiber reinforcement and surface hydrophobic modification technology.
