Preparation and Characterization of Red Mud-Based Geopolymer Composited with Rice Husk Ash for the Adsorption of Bromocresol Green in Aqueous Solution

Geopolymer-based industrial waste as red mud (RM) was successfully obtained in the presence of different loadings of rice husk ash (RHA). During the preparation, the added amounts of RHA in the geopolymer composition were varied from 10 to 50 % when the mass ratio of binder solution (Na2SiO3) and activated alkali-metal solution (NaOH 7 M) were 2.5 and the curing condition was fixed at 333 K within 24 h.

Synthesis and Study of Properties of Geopolymer Materials Developed Using Local Natural Raw Materials and Industrial Waste

This paper describes the synthesis of geopolymer materials using thermally modified clay rocks of Georgia and metallurgical granulated blast-furnace slag; as well as the study of their physical and mechanical properties, durability, and corrosion resistance in aggressive solutions.The methods of chemical, X-ray phase, differential thermal analysis and SEM were used.
