The applicability of a granulated coal ash to construction material (geomaterial) was investigated to promote the recycling. Especially, the characteristics of the individual particle such as shape, physical properties and strength were measured. The features of the granulated coal ash were clarified in comparing with the result of the natural sands. The following conclusions were obtained. (1) The aspect ratio Ar of the granulated coal ash is lower and roundness coefficient Rc is higher than those of natural sands. (2) The void ratio of the granulated coal ash become high because of larger roundness coefficient Rc and containing intragranular voids. (3) It become clear that single particle crushing strength of granulated coal ash is lower than that of natural sands, however, its strength increase as the curing days, in the observation for 900 days. (4) It is found that single particle crushing strength of granulated coal ash doesn't depend on the particle size. (5) It is confirmed that the Weibull modulus mf of granulated coal ash is larger than that of natural sands, and the variability of maximum crushing strength is small. (6) It is found that the Weibull modulus mf doesn't depend on the particle size and curing days.
