The determination of curve fitting functions of moisture storage in the porous material

ZHONG Huizhi1,LEI Bo2,FENG Ya1(1.China Southwest Architecture Design & Research Institute,Chengdu 610042,China; 2.School of Mechanics Engineering,Southwest Jiaotong University,Chengdu 610031,China)  
The moisture storage function is the basic of achieving the relevant parameters and the transfer coefficients of the moisture transfer,and is also the basic of the dynamic analysis.In this paper,the comparison of three kinds of moisture sorption isotherm and one kind of water retention characteristic have been presented along with the experimental data of a new thermal insulation mortar.The results show that the data calculated by FSEC model are the closest to the experimental data in the hygroscopic moisture range;the relative errors of all data are less than 4%.And the data calculated by Gauss model are the closest to the experimental data in the all moisture range.
