dc.description.abstractSustainable development is being practiced to meet the needs of the present without compromising the ability of future generations to meet their own needs. In geopolymer, researchers use waste materials as the source of geopolymer. Over 65% of the crust of the earth consists of aluminosilicate minerals. Sediment is one of the major waste and sediment has the higher possibility for manufacturing of geopolymer due to their low cost and availability. The alkaline activator used in this preliminary study is Sodium Hydroxide (NaOH). 9 mix design have been tested L9 Taguchi Array. The four factors were NaOH (5M, 8M, and 10M), moisture (30%, 35%, and 40%), curing temperature (50°C, 60°C, and 80°C) and curing days (3, 7, and 14 days). The obtained results were evaluated by Design of Experiment (DOE) method to determine the optimum level of each factor. The optimum level of curing temperature was 80°C to achieve the maximum compressive strength. Meanwhile, the optimum NaOH concentration was obtained at 10M NaOH concentration. The moisture had no significant to determine the compressive strength. Furthermore, the optimum oven curing time was 72 hours. Microstructural behavior was also analyzed using Scanning Electron Microscopy (SEM) and X-Ray diffraction (XRD) in this study. Results show that the microstructural of ground sediment had a good potential as a source material in geopolymer. Thus, this research study focusing on NaOH activated ground sediment geopolymer.
