The generation of cast-in-place lightweight gypsum wall changes the Construction form of the inside insulation wall ,using the industrial by-product as the main raw material and the whole cast-in-place construction way has a significant meaning for improving the integrality and anti-seismic property of the wall, improving the people's living level,using the industrial waste,protecting the environment and saving the land resources and energy sources.

Cast-in-place Lightweight Gypsum Wall is a new green wall that industrial by-products are used as the main raw materials and the spot construction is employed by casting in place for construction, which improves the integrity and seismic performance of the wall. Focusing on the cast-in-place light gypsum wall, the body comprehensive evaluation model is established based on the theory of fuzzy matter-element in the background of "Performance", "Technology", "Economy" and "Environment" for evaluation index system. Furthermore, AHP, expert scoring and other methods are used to determine the weights of each value in the evaluation index system.And the principle of comprehensive evaluation is the maximal subjection degree.These will serve as a theoretical underpinning to find the weakness of such walls and explore the market and application prospects.
