GEO POLYMER CONCRETE
[EIRI/EDPR/4576] J.C.: 2793XL
INTRODUCTION
Geo polymer concrete is an innovative, eco-friendly construction material.
It is used as replacement of cement concrete.
In geo polymer concrete cement is not used as a binding material.
Fly ash, silica-fume, or GGBS, along with alkali solution are used as binders.
IS THERE A WAY TO USE OPC WITHOUT ENVIRONMENTAL IMPACT?
Replacing some limestone with fly ash and blast furnace slag called as blended cement
Using carbon dioxide emission captures and storage (CCS)
Accelerated carbonation where CO2 penetrate concrete reacting with Ca(OH)2 in presence of H2O forming CaCO3
