摘　　要：分析了潮湿环境对高强混凝土性能的影响,提出了将高性能合成纤维融入高强混凝土中,以形成合成纤维增强高强混凝土。通过将16%的粉煤灰和9%的硅灰等量替换水泥加上湿热养护的方法,提高高强混凝土的强度、耐久性和抗裂能力。研究结果表明,基于湿热养护方式,纤维掺量为1.5%的组展现最高抗压强度,达116.55MPa,增长了11.5%。The effect of wet environment on the performance of high strength concrete is analyzed,and it is proposed that high performance synthetic fiber is integrated into high strength concrete to formsynthetic fiber reinforced high strength concrete.By replacing cement with 16%fly ash and 9%silica fume,the strength,durability and cracking resistance of high strength concrete are improved.The results showed that the groupwith 1.5%fiber content showed the highest compressive strength of 116.55MPa,which increased by 11.5%.
