OXIDATION OF CARBON FIBER SURFACES FOR IMPROVEMENT IN FIBER-CEMENT INTERFACIAL BOND AT A HYDROTHERMAL TEMPERATURE OF 300 DEG C

Carbon fiber oxidized by a hot naoh solution appears to have potential for use as reinforcement in high-temperature cementitious material systems. It has been determined that active carboxylic acid and na-labeled carboxyl functional groups introduced on the fiber surfaces by extensive oxidation react preferentially with calcium ions released from cement in a hydrothermal environment at 300 deg c. This interfacial interaction leads to a linkage between the fiber and the cement matrix, thereby enhancing the bond strength. (Author/TRRL)
