摘要:

摘要:研究分析了粉煤灰掺量对混凝土抗氯离子渗透性的影响,并进行了电镜、X衍射和压汞测孔微观分析.结果表明:粉煤灰掺量对混凝土抗氯离子渗透性的影响随龄期不同而不同:7 d龄期时,随着粉煤灰掺量逐渐增加,混凝土的抗氯离子渗透性能逐渐降低;28 d、56 d龄期时,粉煤灰掺量小于40%时,随着粉煤灰掺量的增加混凝土的抗氯离子渗透性能逐渐增强,掺量超过40%后,电通量值有所增大.因此,40%的粉煤灰掺量是混凝土抗氯离子渗透的极限点.
Abstract:
A series of experiment were conducted to analyze the influence of adding volume of fly ash on the antichloride penetrative property of concrete by microanalysis of electronic microscope, diffraction and pressing hydrargyrum. the effect of adding volume of fly ash on antichloride penetrative property of concrete changed with the age of concrete. the antichloride penetrative property of concrete decreased gradually with the gradually increase of fly ash at the age of 7 d,and at the age of 28 d and 56 d,antichloride penetrative properly of concrete is enlanled with the adding volume of fly ash below 40%, and electricflux increased when adding volume is over 40%. Hence, adding volume of fly ash of 40% is the highpoint for the antichloride penetrative property.
