摘要：
This paper develops mixes for slag modified fibre-reinforced metakaolin-based geopolymer composite (GPC) to address slow setting time and efflorescence. The fresh properties of the mixes showed that slump and slump flow reduced with increasing slag content. There is an increase in compressive and flexural strength as the slag content increases. The visual observation on the hardened specimens shows no efflorescence at the age of 28-day. The control sample (Mix 1) and Mix 2 are 3D printable. The mix with slag content shows better structural build-up.
