Abstract
| This work presents a way to valorize red mud, rice husk ash, a major waste from combustion of rice husk and white clay as a raw material for the production of geopolymers that are environmentally friendly and only requires low energy to make and have diverse potential application. A wide range of parameters in the geopolymerization reaction, consisting of RHA to RM weight ratio, variable concentration of sodium hydroxide. RHA, RM and white clay ratio and sodium silicate solutions were examined to understand their influence on the compressive strength of the end products- RHA, RM and white clay based geopolymers. The geopolymers were characterized by X-ray diffraction, FTIR. The result of compression testing indicates that the compressive strength of the studied RHA, RM and white clay based geopolymers are in the range of 2.2 to 19.5 Mpa, which is comparable with that of almost all Portland cement. In addition, the utilization of RHA, RM and white clay based geopolymers in practice is able to bring both environmental and economic advantages. The finding suggest that these wastes can be reused to make geopolymers that can find application in civil infrastructure constructions. |
