Cover Story: Foamed concrete contains numerous pores which strongly affect the material characteristics and properties. An appropriate investigation is necessary for more detailed understanding of foamed concrete, and the micro-CT imaging and quantitative methods are used to examine the material. Using the methods, the pore characteristics and the relative density of solids are examined, and the material properties of the foamed specimen are numerically computed. The results demonstrate the effects of the pore characteristics on the local and global properties of foamed concrete and can be used for developing the material with lower thermal conductivity by minimizing the strength reduction.
