Abstract:Palm Oil Fuel Ash (POFA) as an agro-industrial waste has potential applications in the construction industry. Using POFA to produce extracted precipitated silica is another step toward improving the performance of mortar and concrete with cost-effective biomass waste. This study investigates precipitated silica extracted from POFA as an additive for mortar. Mortar mixtures containing various percentages of precipitated silica (PS) and silica fume (SF) with 2%, 4%, and 6% by weight of cement were cast and studi… Show more
