Abstract
Nowadays, cement is a significant element in the construction industry. Agriculture waste material can help to enhance the properties of fresh and hardened cement mortar. Banana peel is one of the agriculture waste that can turn to banana peel ash (BPA) to be use as pozzolanic material in civil construction that can reduce cost and environmental pollution due to its potassium element. In this study, the properties of the cement mortar are investigated during fresh and hardened condition. Throughout the study, in fresh state, the results show BPA contains highest potassium that can enhance properties of cement mortar. It shows that cement paste didn’t show any expansion after been added with BPA into the mixture. Hence, it will increase the workability of cement paste. In addition, in hardened state, the data show that during hydration process, the strength of cement mortar added with BPA increase. All BPA admixture which is 1%, 2% and 3% obtained highest strength compare to control mix during 3 days curing. However, during later age the result show the strength keep increase but control mixture obtained the highest strength compare to all BPA admixture. Another results show that the gap for interfacial transition zone (ITZ) for cement mortar decrease when more BPA been add to the mixture. The strength of cement mortar will increase if the gap for ITZ decrease. More percentage of inclusion BPA can be use in the future to obtain highest strength in cement mortar.
