| description | This research briefly determines and compares the test methods on assessing the pozzolanic reactivity. As the application of concrete in this industry had been widely known and applied, the replacement of cement content is needed as cement had been contributed to the higher amount of releasing gas carbon dioxide (CO2) to the atmosphere. As Spent Bleaching Earth is one of the solid wastes that need to be reduced, the recycle product of SBE which is Spent Bleaching Earth Ash (SBEA) can be the solution. The utilization of SBEA in construction industry is widely justified, however, the calcination process is adding to the SBEA and questioned the capability of the calcined SBEA to partially substitute the cement content. Therefore, there are two (2) main objectives of this study which are to determine the pozzolanic reactivity of calcined SBEA using the Strength Activity Index, Frattini Test and X-Ray Diffraction (XRD) methods and to investigate the pozzolanic reactivity of uncalcined and calcined SBEA. This study is focus on SBEA where the samples used are divided into control mortar, uncalcined SBEA, and calcined SBEA. The calcined SBEA were obtained from the heating process in the furnace at the laboratory for 700˚C in 4 hours. The research study had been found that the calcined SBEA shows less improvement of pozzolanic reactivity compared to uncalcined SBEA. The reduction of pozzolanic reactivity is due to two (2) main factors which are the percentage of water absorption and the intensity of the silica in the samples. Therefore, the calcination process of SBEA is not needed to improve the pozzolanic reactivity of SBEA. |
