Description 350-357
Infrastructural development requires large quantity of Ordinary Portland cement. Its manufacturing process emits
enormous amount of carbon dioxide, thereby deteriorating the environment. Thus, an alternative binder known as
geopolymer, developed using alumino-silicate rich materials like fly ash, silica fume, metakaoline etc., activated by suitable
alkalis may serve as a substitute to conventional cement. The present research work focuses on preparation of ground
granulated blast furnace slag based geopolymer mortar with ambient temperature curing at 27°C at low concentration of
alkali activators. Compressive strength of geopolymer mortar at different concentration of activator and microstructure
isstudied. The concentration of alkali activators is optimized by trials in laboratory and maximum compressive strength of
64.29 MPa is achieved.
