Synergic effect of metakaolin and groundnut shell ash on the behavior of fly ash-based self-compacting geopolymer concrete

The sustainable self-compacting geopolymer concrete (SCGC) production is an eco-efficient concrete with a lower carbon footprint than conventional concrete. This experimental work was performed on the fly ash based SCGC mixtures which blended metakaolin and groundnut shell ash individually and combi...
