Compressive strength of metakaolin concrete for grade M20. In addition, the strength loss of concrete, with an increasing metakaolin level from the 10% replacement was found to be consistent with all the water/binder ratios, which indicate that natural pozzolans like metakaolin have little or no effect on the water demand of concrete.
