Based on the previously developed building sealing materials, study the impact of material components and processes on the performance of building sealing materials to achieve optimal design of building sealing materials; use self-designed devices to establish testing methods and evaluation indicators for building sealing materials; study the impact of environmental conditions and construction methods on the sealing performance of building components, formulate construction technical regulations; conduct application technical and economic analysis of sealing materials. Through the above research, new building sealing materials and supporting application technologies suitable for building door and window joints and splicing joints of prefabricated building components have been obtained, laying the foundation for their popularization and use in construction projects.

The new sealing material has the advantages of high efficiency and simple construction, excellent performance, and low cost. In terms of social benefits, it can well solve the long-standing leakage problem in construction projects, help resolve social conflicts, and promote harmonious social progress. In terms of economic benefits, after adopting this technology, the construction efficiency will be greatly improved, and a lot of labor and labor costs can be saved. After the splicing joints of doors, windows and prefabricated components are sealed, there is no need to be waterproofed, which can save considerable material costs. At the same time, due to the reduction of working procedures, labor costs can also be reduced and the construction period can be shortened. Therefore, after adopting this technology, the overall cost of sealing building door, window joints and component splicing joints is reduced. In terms of environmental benefits, this material is green, energy-saving and environmentally friendly. This material uses a large amount of desulfurized gypsum, slag powder, and fly ash in the cementitious material, which can absorb a large amount of industrial waste, reduce environmental pollution caused by industrial waste residue, and provide a new way for the resource utilization of industrial waste residue.
