EFFECT OF METAKAOLIN ON COMPRESSIVE STRENGTH

2019-4-21  The result of some physical properties of MK is presented in table 2. The loss on ignition (LOI) which is a measure of organic and carbonate content and sediment is 1.76 % which is below the10 %, the maximum specified by ASTM C618 (2012). The low LOI indicates its high reactivity when blended in concrete. The specific gravity obtained was 2.50, while that of Ashaka cement is 3.15. This indicates that MK is lighter than cement and more volume of MK will be required to replace equal weight of cement in concrete. The pH of MK is 9.5, this value shows that MK is neither acidic (pH11.0) but neutral (pH between7-11). This implies that MK can also be used in concrete without much concern for durability related problem. The result of oxide composition test conducted on MK
