Impact of added water and superplasticizer on early compressive strength of selected mixtures of palm oil fuel ash-based engineered geopolymer composites

This paper investigates and presents a study on the comparative effects of added water and naphthalene-based superplasticizer (SP) on the compressive strength and microstructure of the developed palm oil fuel ash engineered geopolymer composites (POFA-EGC). Three differently prepared 50 mm × 50 mm × 50 mm specimens (with 10% water, with 10% SP and with 5% SP & 5% water) were used to study the synthesis of POFA and alkali-activating solutions (8...
