Study on static moisture absorption characteristics of porous humidity regulating ceramic building materials

In order to improve the research accuracy of hygroscopic properties of building materials, a study method of static hygroscopic properties of porous humidity regulating ceramic building materials is proposed. Firstly, the materials needed for the preparation of porous humidity regulating ceramic building materials and the preparation instruments used are analysed, and the materials are prepared according to the process flow of material preparation. Secondly, the structure and characteristic parameters of material samples are analysed, and the fluid relationship of porous materials is calculated. Finally, the static moisture absorption characteristics of the material are studied from two aspects: moisture absorption height and moisture absorption rate. The results show that the smaller the average particle is, the greater the water absorption height is; the larger the particle diameter is, the slower the water absorption rate decreases. The characteristic research accuracy of this method is more than 90%.
