Three kinds of polymers, polymethyl acrylate emulsion(PAE), polyvinyl formal solution(PVFO), styrene acrylate copolymer emulsion(SA) are chosen to study the effect of polymer in steel fiber reinforced cement composites(SFRCC). The experimental results show that the bonding properties in SFRCC are remarkably improved after the addition of three kinds of polymer. The interfacial bonding strength is obviously enhanced with the addition of polymer contents, and is gradually steady or cut down slightly when the polymer content excesses 15%. In the meantime, the toughness of SFRCC is greatly advanced when the polymers are doped. At last, the effect mechanism of polymer in SFRCC is put forward.
