Fiber-reinforced cement composites (FRC) were prepared from polyvinylalcohol (PVA) fibers and polvacrylonitrile (PAN) fibers, and various polyacrylamide (PAM) as a coupling anent. It was found that among various types of PAM, high molecular weight polyacrylamides (PAM) having polar ionic groups were effective as coupling agent for cement and fibers in slurry state. Particularly, anionic PAM for PVA fiber system and cationic PAM for PAN fiber system were arrived to be the most effective coupling agents, respectively. This is considered to be resulted from the polarity of the side groups existing in the fibers. It was also notable that addition of aluminum salt enhanced the coupling of cement to the fibers by improving dispersion of the fiber in the slurry state. Conclusively, the existence of coupling agent is a key factor for the preparation of FRC by slurry method.lso confirmed that the content of
