Abstract
The material of FANR is a waste material from the power plantation of Nagan Raya, Acheh, Indonesia. Some information recorded that the particle of FANR had the chemical content of Si, Fe, Al, and, Ca with the misty surface. However, the misty surface of FANR suspected to influence the properties of mortar. So, this study aimed to evaluate the use of FANR as a cement replacement in the properties of mortar. The investigation was conducted with the FANR of 5%, 10%, 15%, 20%, and 25%, respectively with the water to cement ratio of o.55 and 0.50, respectively. The parameter in this study included chemical composition, workability, setting time, and compressive strength. The results showed that the FANR had a chemical composition of Si, Fe, Al, and Ca with the particle shape of sphere and misty surface. Due to these characteristics, the FANR had a decreased workability and shorter the setting time in the fresh mortar. Finally, the 5% FANR with w/c ratio of 0.50 provided the highest compressive strength at 28 days. Whereas, the use of FANR with more percentage was considered to improve the compressive strength after 28 days. It concluded that the use of FANR as a cement replacement affected on the properties of mortar.
