摘要
偏高岭土是高岭土矿在700°C高温下煅烧的产物。本文测定了不同水灰比、内掺不同掺量偏高岭土的混凝土试样的氯离子导电量,并与基准混凝土相比较。试验结果表明,在混凝土中掺入适量的偏高岭土能有效降低混凝土的氯离子导电量。在相同水灰比下,混凝土试样的氯离子导电量随龄期的增加而降低、随混凝土中偏高岭土掺量的增大而减小;在相同的偏高岭土掺量下,混凝土试样的氯离子导电量随水胶比的降低而降低。
Metakaolin is the calcined product of Kaolin mineral at 700℃.The effects of Metakaolin and W/B on the charges passed of concrete were studied in this paper.The results showed that the charges passed in concrete decreased with the curing age increaseing and the content of metakaolin increaseng in cement at the same W/B ratio, and when other factors fixed the charges passed decreased with the W/B ratio decreaseing.
