dc.description.abstractGeopolymer is new class of cementitous materials, synthesized by mixing the almino-silicate sources with alkaline activating solution. It is an eco-friendly innovative alternative to cement which utilized various waste materials that are not reused in industries and urgent to dispose of. The rice husk ash is an agricultural waste which is suitable for geopolymerisation. In this study, influence of nano-metakaolin on rice husk ash based geopolymer has been investigated. Eighteen mixes of geopolymer were prepared with three different molar concentrations of alkaline activator (12M, 14M and 16M) and different proportion of nanometakaolin (0% to10% @2% increment). Thee compressive strength was tested after 3, 7, 14 and 28 days of curing. The X-ray diffraction test was performed on the rice husk ash, powdered sample of mixes K1, K7, K13 & K16. The powdered samples were collected from remnants of geopolymer after 28 days compressive strength test. The Results reveal that compressive strength of geopolymer increases for all curing ages when the concentration of alkaline activator is raised from 12M to 16M but the proportion of nano-metakaolin increases the strength up to certain limit. Beyond that there was reduction in compressive strength. The compressive strength results were accomplished by X-ray diffraction analysis. The geopolymer mortar prepared using 16M concentration of alkaline activator and 6% proportion of nano-metakaolin is recommended for the maximum compressive strength.en_US
