Compressive strength, porosity, and sorptivity of blended Palm Oil Fuel Ash (POFA) concrete containing silica fume in peat water

Abstract Blended Palm Oil Fuel Ash (POFA) concrete has the potential for application in organic acid environments such as peat land. However, there is a need to improve resistance of blended POFA using silica fume pozzolanic material. There are limited studies admixed with exposure. In this study, compressive strength, porosity, and sorptivity been investigated by exposing samples water. Portland Composite Cement (PCC) similar target strength was used control mix. The contained 0%, 20% 40% cement substitute. Micro or added concentrations 10% each mixture. specimens attack were measured porosity development at 7, 28 91 days. Compressive mix declined, while PCC PCC-POFA containing increased Porosity OFA followed same trend strength. Thus, better water than that
