| 摘 要： | 我国高岭土资源丰富，偏高岭土应用于混凝土有将会很大前景。本文对比研究了复掺偏高岭土对混凝土抗压强度的影响。研究表明在水胶比为0．31下，偏高岭土与粉煤灰总掺量为35％（偏高岭土掺量为8％）时更能充分发挥偏高岭土的活性。合理的偏高岭土掺入对掺粉煤灰混凝土早期抗压强度有提高明显，抗压强度提高可达47％。

| Abstract: | The influence of Composite admixing Metakaolin on the Strength of Concrete was studied in this paper. The results show that as the ratio of water to cement is 0.31, the activity of metakaolin can be brought into full play when the addition of metakaolin and fly ash is 35 % （ 8 % metakaolin content ） . The appropriate dosage of metakaolin can significantly increase the early compressive strength of fly ash concrete, and the increase of compressive strength is up to 47%. |
