STATISTICAL MODELING OF GEOPOLYMER MORTAR

Cement is a fundamental raw material used in construction. Production of cement releases large amount of CO2 which is a major cause for the global warming issue. Hence calculated percentage of cement can be replaced by other materials such as fly ash, rice husk ash, Metakaolin, silica fume etc. Fly ash is one of the most normally preferred substitutes for cement because concrete workability and durability are enhanced by fly ash by their small size and round shape. A mathematical model was constructed using SPSS software for the strength characteristics like compressive strength, split tensile strength when cement is fully replaced with fly ash .Fluid/binder ratio is the main parameter which influence the strength characteristics. A comparative study between the results obtained from the laboratory and SPSS has been made and it is found that the differences between these two values are minimum.
