year we are producing billion tons of concrete. Production of cement is responsible for too much of CO2 production, in other
words it is also responsible for global warming. Mostly India is facing the problem of pollution.
Researchers have done a great job and found many ways to replace cement. For making geopolymer concrete by products of
different industries may be used like. Fly ash, rice husk. In this investigation geopolymer concrete is prepared with GGBS.
GGBS is a by-product of steel industry.
