To examine the possibility of recycling scrapped glass fiber-reinforced plastics(FRP), its fine powder and ash were produced and mixed into concrete. River sand was used as fine aggregate of the concrete, creshed stone as coarse aggregate, and naphtalene-derived and carboxylic acid-derived high range water reducing agents were used as admixtures. FRP fine powder was made by pulverizing molded FRP, and FRP ash was obtained by calcinating it at 800C. In the mixed concrete, 5% of cement was replaced by FRP fine powder of FRP ash. The mix of concrete was W/C:35% and S/A:51.8%. Unit contents of the concrete containing FRP fine powder were cement:486kg/m3, FRP fine powder or ash:24kg/m3, fine aggergate;860kg/m3, coarse aggregate:806kg/m3, and water :170kg/m3. Setting time test, drying shrinkage test, accelerated carbonation test, and compressive strength were carried out on the seat concrete to investigate the effects of the kind of fine powder on (1)slump flow and air content, (2)compressive strength, (3)drying shrinkage, and (4)carbonation. Concrete, in which 5% of cement was replaced by FRP fine powder or ash, showed the following results regardless of the kind of fine powder. (a)Slump flow decreased. (b)Compressive strength was 90-103% of that of control. (c)Drying shrinkage (26 weeks) was 114, 126% of the of control. (d) carbonation depth (26 weeks) was not recognazed. These proved the possibility of recycling scrapped FRP as an aggregate for concrete in the form of fine powder or ash.
