Laminated slabs are prefabricated panels and cast-in-situ reinforced concrete layers that are laminated to form a prefabricated monolithic floor slab. The composite floor slab has good integrity and the upper and lower surfaces of the slab are flat, making it easy to decorate the facing layer. It is suitable for high-rise buildings and large-bay buildings that require high overall stiffness. Ceramsite boards are wall panels produced with high-strength ceramsite as the core aggregate, adding self-developed polymer additives and patented technology.
