Peat is superficial deposit or soil with high organic content. The soil is highly compressible and acidic. The organic acidic water in swampy peat soil consists humic acid that is potentially corrosive to concrete and metal structures. Geopolymer is a material using waste from agro-industry such as fly ash (FA) and palm oil fuel ash (POFA) that is activated with alkaline solution. In this research, the acid resistance of geopolymer mortars from fly ash and palm oil fuel ash was measured by change in compressive strength and porosity. The samples were subjected to distilled water and acidic peat water. The OPC mortars showed a considerable decrease in compressive strength after subjected in peat water for up to 180 days. There was a fluctuated trend of geopolymer FA and a high decrease in compressive strength of geopolymer POFA after subjected to the peat water. The porosity of the geopolymer specimens was higher than the control mortars. However, it was observed that the geopolymer FA is more resistant to the acidic peat water than the geopolymer POFA due to stable aluminosilicate bonding.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
