Geopolymer as one of the breakthrough in the searching of ordinary portland cement/concrete substitution provides many options and possibilities of using different types of pozzolanic or alumina-silica materials.
Methodology Material The basic material used for geopolymerization in this experiment is metakaolinite which was obtained by calcining kaolinite at 850ºC for 6 hours [4].
All chemical materials were supplied by PT.Bratachem® Bandung, Indonesia.
