The main issue which geopolymer paste often performed is the rapid binding time. C class fly ash specifically has the most rapid binding time. This research is aimed to explore the potential of seashell waste materials utilization on fly ash-based geopolymer paste. The research methodology which used for this particular work is the laboratory experimental approach. During the experiment, several paste sample were prepared in the mold with diameter of 2,5x5cm. The standard code which used to determine the binding time were ASTM C 191-04a. While ASTM C 39-04a standard code was used to determine the geopolymer paste compressive strength. The experiment sample tests were conducted at the age of 3 days, 28 days, and 56 days after the curing time of the geopolymer paste. The result of the above mentioned experiment process showed that seashells waste material has 97.59% of CaO, 0.29% of Al2O3, 1.12% of SiO2 and 0.39% of Fe2O3 content. By looking at this chemical composition, seashell waste materials could potentially use as the geopolymer binder which has an optimum binding time. [ABSTRACT FROM AUTHOR] |
