ABSTRACT
Polymer modified cement-based materials and fiber reinforced cementitious composites are both widely used in civil engineering applications. Both show great advantages, especially in repair and rehabilitation. The work reported here, however, deals with polymer modified fiber reinforced cement based composites (PM-FRC) that is, combined used of fibers and polymers in the same system. This paper reports the quantitative study of all the three additives each taken with three settings, namely, steel fiber (1.0%, 1.5% and 2.0%), acrylic emulsion polymer (1.0%, 2.5% and 4.0%) and silica fume (5.0%, 6.0% and 8.0%). The other two control variables were chosen as water-cement ratio (0.42, 0.50 and 0.60) and aging (3, 7 and 28 days). In this study, steel fiber reinforced polymer modified concrete (SFRPMC) was produced with the addition of acrylic emulsion polymer (
