摘　　要：粉煤灰掺入到混凝土中，由于其活性效应、微集料填充效应、形态效应以及吸附效应而使混凝土的密实度和对氯离子的固化能力得以提高，降低氯离子的渗透系数，提高混凝土的抗氯离子侵蚀能力。粉煤灰的掺量和细度对混凝土的性能有一定的影响。When fly ash is mixed into concrete, because of its active effect, form effect, collect material effect and absorption effect, the density and solidification ability to chloride icons of concrete are advanced. The coefficient of chloride icons penetration is brought down, while ability of the resistance to penetration of chloride icons is brought up. Volume and fineness of fly ash can affect concrete＇s performance.
