Korosi Dan Leaching Beton Blended Pofa Dengan Campuran Silika Di Air Gambut
ABSTRACT Blended concrete is a mixture of aggregate and blended cement. Substitution of cement into mixed cement has an impact on increasing the pozzolanic reaction in cement. The silica content in Palm Oil Fuel Ash (POFA) is the element most needed to increase the reactivity of pozzolans. A treatment is required to obtain pure silica in POFA through the sol gel precipitation process. The cont…
