This paper presents the results of a study on fly ash-based geopolymer concrete.
The test parameters covered certain aspects of manufacture of geopolymer
concrete. The paper also reports the stress-strain behavior of the concrete with
compressive strength in the range of 40 to 65 MPa. Tests were carried out on
100mmx200mm cylindrical geopolymer concrete specimens. Test results show that
a good agreement exists between the measured stress-strain relations of fly ashbased
geopolymer concrete and those predicted by a model developed originally for
Portland cement concrete.
