Pemanfaatan Limbah Karbit Sebagai Bahan Campuran Beton
ABSTRACT Fly ash is widely used as concrete's builder because it contains quite high silica (SiO2) approximately 58,20%. Fly ash can increase concrete power pressure and contains characteristic like cement. Fly ash contains low CaO approximately 3,30% so it needs other material to increase CaO on concrete.
