Early Strength Characteristics of Palm Oil Fuel Ash and Metakaolin Blended Geopolymer Mortar

In this paper, the early strength behavior of Metakaolin and Palm Oil Fuel Ash (POFA) based geopolymer mortar was investigated for the purpose of exploring the utilization of POFA which is a waste material generated from production of palm oil. Geopolymer mortar was prepared by activating metakaolin combined with POFA at 0%, 30%, 40%, 50%, 60%, 70% and 80% replacement levels in NaOH and Na 2 SiO 3 medium. The mortar specimens were tested for...
