The mixture of aluminosilicate material such as fly ash, silica fume with an alkaline solution such as sodium hydroxide & sodium silicate completes the geopolymerization process and forms an activated alkaline solution that has the binding property. This activated alkaline solution is mixed with white clay and produces the geopolymer brick. The various trial mixes are worked out with an AAS/FA ratio between 0.4 to 0.5, Na2SiO3/NaOH ratio between 2 to 3, and molarity of alkaline solution between 12M to 16M. The various trial mix bricks will be prepared and oven cured at 70°c ambient temperature. The brick is then analyzed for compressive strength and Durability tests. The maximum compressive strength is achieved up to 5.1 N/mm2 & water absorption of 5% when it is heated at 70°c for 7 days. Microstructure Analysis tests such as X-Ray Diffraction Test (XRD) is carried out on material. The geopolymerization reaction resulting in a formation of new product with different microstructure.

Alkaline solution, Microstructure of the material, Geopolymerization, etc.
