偏高岭土的活化及性能研究

Research on the Activation and Performance of Metakaolin

研究了煅烧温度、Al2 O3+SiO2 含量等对偏高岭土活性的影响以及偏高岭土对水泥性能的影响。经适宜温度煅烧所得的偏高岭土具有较高的活性 ,对改善水泥的强度等性能具有积极作用 ,是一种理想的高活性掺合料。

Here dealt with is the effect of the calcination temperature and the content of Al 2O 3+SiO 2 on the activation of metakaolin and that of metakaolin on the performance of cement. It is told here that metakaolin cacined under proper temperarure has relatively high activation and positive function on the improvement on cement strenghth and other performance and therefore,is a kind of ideal high active admixture.
