    “…[Image: see text] In this study, geopolymer originating from locally industrial byproducts as red mud (RM) was successfully prepared in the presence of different loadings of rice husk ash (RHA) used for the adsorption of methylene blue (MB) in wastewater. During geopolymerization, various mixing amounts between RM and RHA were conducted when the weight ratio of binder solution/activated alkali-metal solution (Na(2)SiO(3)/ NaOH 7 M) was 2.5 and the curing temperature was set at 60 °C for 24 h. …”
