Adiabatic temperature rise of metakaolin mortar
Using MK (metakaolin) in concrete has gained momentum in recent years. This paper investigates the temperature rise in mortar containing MK during the first 48 hours of hydration. Mortar specimens in the form of 300 mm cubes were prepared. The PC (Portland Cement) was partially replaced with with between 0 % and 25 % MK (by mass) and between 0 % and 25 % FS (fine sand). The mortar had a proportion of one part binder to 3 parts aggregate sand. The water to binder (PC + MK) and (PC + FS) ratios were kept constant at 0.55 for all mortar mixes. The results show that the peak temperature increases with increase inMK content up to between 10 % and 15 % MK, beyond which the peak temperature starts to decrease. However the peak temperature still remains higher than that of the control (0% MK) at 20 % MK but drops below the control peak temperature at 25 % MK. Also the time taken to reach the peak temperature is reduced in the presence of MK indicating acceleration of hydration.
