✦ Synopsis

The tensile strength, modulus and ductility of carbon fiber reinforced cement paste were increased by ozone treatment of the fibers prior to using the fibers. Increases were observed whether or not the paste contained methylcellulose/silica fume/latex. The ozone treatment involved exposure to O3 gas (0.3 vol.%, in air) for 10 min at 160°C. copyr&r o 1996 EIXVWSCWIC~ ud
