摘要
The bond strength between carbon fiber and cement was enhanced by oxidizing chemical treatments, with ozone treatment giving the greatest effect. The effect was accompanied by an increase in the electrical contact resistivity of the interface. These effects are mainly attributed to oxygen-containing functional groups on the fibers due to the treatments. The bond strength and contact resistivity were also increased by polymer (latex, methylcellulose) admixtures in the cement mix, but the effects were less than those of ozone treatment.
