摘要: 采用实验室模拟酸雨侵蚀试验,研究了酸雨环境下水胶比、粉煤灰掺量、pH值和SO2-4浓度这四个指标对粉煤灰混凝土抗压强度的影响,并用灰关联法分析了各因素对抗压强度的影响程度.结果表明:抗压强度随SO2-4浓度、粉煤灰掺量、水胶比的增大而下降,随pH值的减小而下降.酸雨环境下粉煤灰混凝土的抗压强度会显著降低,SO2-4浓度对其影响最大.

关键词: 酸雨腐蚀;粉煤灰混凝土;抗压强度;灰关联分析

Abstract: By laboratory simulated acid rain erosion test, the effects of every factor such as water binder ratio, fly ash content, pH value and SO2-4concentration on the compressive strength of fly ash concrete was studied.And the influence degree of every factor on the compressive strength is analyzed by the gray relative method.The compressive strength decreased with the increase of water binder ratio, fly ash content and SO2-4concentration, and decreased with the decrease of pH value.The compressive strength of fly ash concrete under acid rain will be significantly reduced, and the effect of SO2-4concentration is the most.

Key words: acid rain corrosion;fly ash concrete;compressive strength;gray relative analysis
