Topic: GEOPOLYMER CERAMIC FROM LOCAL CLAY FOR WATER FILTRATION
Abstract: Geopolymers are being considered for a variety of applications including low producing CO2 cements, fiber reinforced composites, refractories and as precursors to ceramic formation. In this study, the geopolymer ceramic paste was made by mixing local metakaolin clay, as a source of aluminosilicate, with different types of alkaline solution and curing in a sealed environment. Then, the amorphous paste was crushed and molded prior to firing at elevated temperature. The objectives of this study are to to study efficiency of geopolymer in water filtration application, to compare the efficiency of geopolymer water filter and commercial ceramic membrane water filter and to analyse the effect of the material used to the synthesis of geopolymer. The study found that the geopolymer can be used as water filter. When comparing to commercial ceramic membrane water filter, geopolymer water filter was worse in terms of efficiency.Lastly, the molar mass of alkali activator used was the major contribute to the geopolymer produce.
