Currently, geopolymer concrete serves as an excellent alternative to traditional plain cement
concrete, as it is produced without using ordinary Portland cement. Different source materials such
as fly ash, rice husk ash, metakaolin, red mud etc. are preferred to act as the main source for
geopolymer production. In this work, a new innovative waste material such as groundnut ash is
utilized as the source material for the manufacture of geopolymer concrete by considering the
strength, economical and availability aspect and 10 M concentration of sodium hydroxide and sodium
silicate gel is used as alkaline liquid activators. During and after the harvest of groundnut, its shells
are used for burning purposes and then its ash is dumped into the landfills as a waste material which
pollutes the land and groundwater to a great extent. A better solution for the above issue is to utilize
groundnut shell ash in concrete to enhance its performance through waste management process.
Here, fly ash is partially replaced by groundnut shell ash in the proportion of 5%, 10%, 15%, and
20%. Glass fiber is added to know the best outcome of the partial replacement of groundnut shell ash.
Geopolymer concrete is cast in the form of tile size of 230 mm x 230 mm x 16 mm and it is cured in
hot air oven for 6 h at 80°C. This work explains in detail about the constituents used to prepare
Geopolymer concrete with partial replacement of groundnut shell ash (GSA) and experimental testing
related to its strength, thermal performance and potential application.
