Limited literatures on the rheological behaviour of slag based geopolymer
mortar and fly ash based geopolymer paste are only available. No information till
date is available on the rheological behaviour of fly ash geopolymer concrete. An
attempt has therefore, been made in the present paper to study the rheological
behaviour of fly ash based geopolymer concrete with a rate controlled concrete
rheometer. It was observed that fly ash based geopolymer concrete can be assumed
to behave Bingham model with a very good accuracy.
