Synthesis of Geopolymer From Water Treatment Residue and Palm Oil Fuel Ash
Type Of : Academic Manuscript
Type : Civil Engineering
This research aimed at synthesizing the geopolymer of water treatment residue and palm oil fuel ash using proper suitable SiO2/Al2O3 ratios by varying the results of compressive strength test and also to examine the quality and microstructure of solidified waste cubes after the maximum of 60 days curing. In the test, the microstructure analysis techniques of XRF XRD SEM were employed. The findings revealed that the proper ratios of SiO2/Al2O3 in synthesizing geopolymer at 2.50 could develop geopolymerization reaction. (In SiO2/Al2O3 test were 1.77, 2.00, 2.50 and 3.00) It was also found that the synthetic geopolymer with optimum compressive strength at 40.56 Ksc. In employing the microstructure analysis technique of XRD and SEM, the changes inside geopolymer structure both before and after the mixing were found. The results can indicate the developing of geopolymerization reaction and synthetic geopolymer products inside the structure of Aluminosilicate source regarding the internal changes as follows; it was found that the peak of Quartz, Potassium Aluminum Silicate (KAlSi2O6), and X-rays diffraction had been superseded by the structure solid of Sodium Aluminum Silicate Hydrate (Na96Al96Si96O384.216H2O; NASH). It was also found Silicon, Aluminum, and Sodium at the same bonding position structure of NASH. As a result, the synthesis of the geopolymer of water treatment residue and palm oil fuel ash can developing strength and changing inside geopolymer structure by appear geopolymer product. Both starting materials can be synthesized and applied in environmental filed.
