Durabilitas Beton Pofa Dengan Penambahan Silika Fume Di Air Gambut

ABSTRACT This study examines the durability of PCC concrete and POFA concrete with the addition of silica fume soaked in peat water. POFA is used as a cement substitute with variations of 0%, 20% and 40% and the addition of silica fume is 10%. The design compressive strength is 20 MPa. Observing the specimens was carried out in normal water for 28 days and then immersed in peat water for 0…
