Foamed concrete with five densities were prepared without sintering, then compounded with the humidity controlling slurry to prepare the sand-based breathing bricks (SBB). The accurate porous parameters of foamed concrete were characterized and quantified by Image-pro Plus 6.0 and Matlab 2015a. The effect of these porous parameters on the properties of the SBB were investigated. The optimal physical, mechanical and humidity controlling properties of SBB were achieved with FCa9 of foamed Concrete. The suitable dry density was 910 kg/m 3 with higher compressive strength of 5.25 MPa, thermal conductivity was 0.08 W·(m·K) −1 , the max moisture absorption was 272.51 g/m 2 and max moisture desorption was 143.09 g/m 2 , which can be used as a wall material for partitioning space to improve indoor air quality.
