Karakteristik Beton Pofa Dengan Penambahan Additive Silica Fume Di Air Gambut

ABSTRACT This research aims to analyze characteristics of POFA (Palm Oil Fuel Ash) concrete by using additive silica fume with PCC (Portland Composite Cement) concrete as control and immersed for 0, 7, and 28 days in peat water. POFA is used as a partial substitute material of cement with variations 0%, 20%, and 40% which silica fume as additional material has constant levels in 10%. Mecha…
