Studi Eksperimental Penggunaan Aktivator Pada Fly Ash Sebagai Bahan Pengganti…

ABSTRACT This research is an experimental study that aims to evaluate the use of fly ash as a cement substitute in Cement Treated Base (CTB) mixtures, using an alkali activator as a binding agent. The fly ash used was derived from coal combustion waste and was combined with an alkali solution consisting of sodium silicate (Na₂SiO₃) and sodium hydroxide (NaOH) in three variations of alk…
