Background
With the gradual decrease and aging of construction workers year by year, materials and construction methods with less popularization labor, high construction efficiency and reliable construction quality in construction engineering become trends, and gypsum self-leveling ground leveling materials are applied and rapidly popularized after 2019. The safe construction thickness of gypsum self-leveling in various systems is not specified by standard at present, and is not determined by a determined method or a calculation model, and the safe construction thickness is determined by experience, so that the ground engineering after construction is subjected to a plurality of quality problems.
The existing floor cushion materials matched with the gypsum self-leveling mainly comprise two major types of heat insulation materials and fine stone concrete, the construction thickness is 5mm, 30mm of cement floor leveling mortar is referenced, 50mm of floor heating is matched, and the like, and the comprehensive cost of a floor system is directly determined by the construction thickness of the gypsum self-leveling. The leveling layer is not a structural layer and is not a final finish, the requirements on structural stress, wear resistance, waterproofness and the like are not high, and the volume stability and long-term crack resistance of the leveling layer are important to be examined. At present, before large-area construction of actual engineering, testing and observation among templates are carried out, the evaluation among templates mainly examines the flatness, apparent state and other apparent indexes of gypsum self-leveling, and for the gypsum self-leveling as a ground system leveling protection layer, the system safety brought by the construction thickness is enough, and the method still belongs to the blank at present. Therefore, before large-area construction, the safe construction thickness of the gypsum self-leveling can be determined through experimental measurement or theoretical calculation, and the method has important significance in improving engineering quality, reducing later maintenance reworking cost and the like. The leveling layer is not a structural layer, so that the theoretical calculation has poor operability, and it is particularly important to find a reasonable method.
