| Abstract: | In this paper,elementary mechanism and experimental results are analysed onthe volume shrin kage characteristics of the wet porous eapillary materials during drying process. Atthe same time, the influence is discussed of mean pore radius and solid matrix strength of the wetporous material,as well as the temperature and velocity of hot air on the volume shrinkage rate onthe basis of the experimental results. |
