Determination of moisture diffusivity in porous materials using gamma-method
In the present study, the gamma ray method was used to examine moisture transfer processes in porous material. The data show that, with this method, the moisture content of the material can be profiled with high accuracy in a nondestructive manner. The advantageous feature is that the method permits high measurement sensitivity and short measurement time. Using this method, moisture diffusivity versus moisture content of the material in cellular concrete samples under sorption and capillary moistening has been examined. The coefficient of moisture diffusion was found to increase appreciably with increasing moisture content in the ranges of low and high moisture content of the material, whereas in the range of moisture content from 5% to 30% only a slight increase of coefficient of moisture diffusion was observed.
