The effect of carbon fiber textile for flexural reinforcement to deter
iorated reinforced concrete floor slab is tested in laboratory by cutt
ing out six specimens from existing structure aged more than 70 years.
The repair method between concrete and carbon fiber textile is used a
s experimental parameter. From the test results, deformation, bond cha
racteristic of carbon fiber textile and the applicability of carbon fi
ber textiles to flexural reinforcement of floor slabs are discussed.
