Thirty one kinds of fiber reinforced cement boards (FRCB) were used to discuss the frost damage from the pore structural point of view. The complexity of a spacial distribution of pore size, expressed by the fractal dimension (D), was found to be correlated with the frost damage index (FD), in the same way as the samples of fired clay roofing tiles. The correlation analysis between FD and the specific pore volume in the respective fractionated pore size ranges has been carried out. As the result, it was found that the pores with larger radii than 50nm cause the frost deterioration of the FRCB materials under the present freezing-thawing condition.
