Study of fly ash based geopolymer concrete cured in ambient condition
MetadataShow full item record
This research studied the properties of concrete using fly ash geopolymer as a low-emission alternative of Portland cement. Inclusion of small quantity of additives enabled curing in normal ambience eliminating the need for elevated heat. Mixtures suitable for curing in ambient condition were found that provided the setting time, workability and strength comparable to those of traditional cement concrete. Blending of additives with fly ash resulted in enhanced engineering and durability properties of geopolymer concrete.
