Polypropylene fiber reinforced concrete improved by using silica fume and acrylic emulsion polymer

The current study aims at exploring the beneficial effect of silica fume (SF) and acrylic emulsion polymer (PR) on enhanced properties polypropylene fiber reinforced concrete (FRC) with supplementary cementitious binder comprised Portland cement, slag, fly ash. compressive strength impact-abrasion resistance were used for estimation engineering while water absorption performance, surface electricity resistance, rapid chloride penetration durability. Experimental results showed that a sole addition SF increased strengths but decreased abrasion-impact resistances modified FRCs, which was just opposite to influence PR. A either or PR could moderately improve durability respectively. However, due complementary interaction between optimal amount PR, mechanical FRCs seemed become significantly improved.
