| Abstract |
| Geopolymer concrete is an alternate material to the conventional concrete. The research on heat cured geopolymers
is well documented by multiple researchers. However, there is very little information available on ambient cured
geopolymer concrete. This paper illustrates the mechanical properties of ambient cured geopolymer concrete
synthesized by activating Class F fly ash and ground granulated blast furnace slag with alkaline solution. Various
mechanical properties like compressive, split tensile, flexural, shear, impact and bond strength of ambient cured
geopolymer concrete were experimentally investigated. Stress-strain behaviour was also studied. Sample durability
tests of conventional and geopolymer concrete were investigated and compared. It was found that many properties
of ambient cured geopolymer concrete were superior when compared to conventional concrete. It was concluded
that geopolymer concrete can be used as high performance concrete in place of conventional concrete for structural
applications with many advantages. |
