Abstract

The research goal is the study of fiber content and fiber type influences on NSC compressive and tensile strengths. fiber type[(steel, polypropylene and glass ) and fiber content were studied. A constant water/binder equals to 0.45 and aconstant binder content =400kg/m 3 were used. the percentages of nano silica[NS] that replaced cement in this research were 0 and1.5%. Polypropylene fiber [PPF] with 12mm length and 4 dosages of 0%, 0.2%,0.4% and 06.% are used. Glass fiber [GF] with 18mm length and 4 dosages of 0%, 0.2%,0.4% and 06.% are also used. Steel fiber [SF] with 50mm length,0.5mm diameter and 4 dosages of 0%, 0.4%,0.8% and 1.2% are used. The results illustrated that 1.5%NS has improvement on normal concrete compressive and tensile strengths. Increasing of SF content from 0.4% to 1.2% has significant improvement on NSC compressive and tensile strengths. PPF and GF addition caused decreasing on NSC compressive and tensile strengths.

纤维种类和掺量对纳米二氧化硅混凝土性能的影响

研究目的是研究纤维含量和纤维类型对NSC抗压强度和抗拉强度的影响。研究了纤维类型(钢、聚丙烯和玻璃)和纤维含量。采用恒定水/粘合剂= 0.45，恒定粘合剂含量=400kg/ m3。纳米二氧化硅[NS]在本研究中替代水泥的比例分别为0%和1.5%。聚丙烯纤维[PPF]长度为12mm，用量为0%、0.2%、0.4%、06。%被使用。玻璃纤维[GF]，长度为18mm，用量为0%、0.2%、0.4%、06。%也被使用。钢纤维[SF]长度为50mm，直径为0.5mm，用量为0%、0.4%、0.8%、1.2%。结果表明，掺1.5%NS可提高普通混凝土的抗压强度和抗拉强度。SF含量从0.4%增加到1.2%，NSC的抗压强度和抗拉强度有显著提高。PPF和GF的加入使NSC的抗压强度和抗拉强度降低。
