Abstract: A method of manufacturing a lightweight thermal insulating cellular cement-based material and a lightweight thermal insulating cellular cement-based board made thereof are disclosed. A binder, an activator, and a blowing agent are mixed to obtain a mixture. The mixture is homogenized to form a cement slurry, which is poured into a mold afterwards. With the help of the activator and an increased temperature of the mold, the cement slurry in the mold will be activated and start foaming and curing to form a cellular cement-based material. The cellular structure is constructed by decomposition of the blowing agent to form a plurality of closed-cell bubbles, which are fixed in the cement slurry during the curing. After the formation, the mold is removed to obtain the cellular cement-based material. The material exhibits high integrity fire resistance and extraordinary insulation fire resistance.

Abstract: Method for preparing porous polyurethane materials with controlled pore size and shape using isocyanates, polyols, and additives, and the porous polyurethane materials prepared therefrom. Method for preparing porous polyimides using at least one polyamine and a dianhydride and the porous polyimides materials prepared therefrom. The porous materials are useful for energy management, such as thermal, impact and vibration energy, and can exhibit improved fire-resistant performance.
