Abstract
This paper investigates the compressive strength, ultrasonic pulse velocity (UPV), and density for cement mortar containing high volume of metakaolin (MK) as partial substitution of cement. Portland cement (PC) was partially replaced with 0-50% MK. Mortar specimens were cured in water at 20°C for a total curing period of 7 days. The results at 7 days of curing indicate that the maximum strength and UPV of mortar occurs at around 10% MK. Beyond 10% MK, the strength of mortar reduces and it starts to be lower than that of the control after 20% MK replacement. Correlation between the various properties is also attempted.
