Abstract

The invention relates to a sealant for prefabricated buildings and its preparation and use method. It is composed of two components AB, and the sealant can be obtained by adjusting the proportion of components A and B according to the construction environment temperature and construction technical requirements. Material, the sealing grout mixed with water has the characteristics of early strength, high strength, micro-expansion, and high adhesion, which can meet the construction requirements for material performance or be used as emergency treatment materials for grouting leakage, ensuring the construction quality of prefabricated buildings and greatly improving the quality of prefabricated buildings. Improve construction efficiency.

Description

technical field [0001] The invention relates to a cement-based building material, in particular to a sealing slurry for prefabricated buildings and a preparation and use method thereof, and is particularly applied to the installation and construction of prefabricated building components. Background technique [0002] In recent years, with the rapid development of my country's economy and the gradual popularization of urbanization, the previous construction process has produced many problems of environmental pollution and energy waste, which are no longer suitable for today's construction and development needs. A new type of prefabricated building structure system was born. Prefabricated buildings refer to the assembly and connection at the construction site after the completion of the component fabrication in the component prefabrication field to complete the construction of the structure. The reliability of the steel bar connection of prefabricated components has a decisive...
