STUDI PEMANFAATAN LIMBAH B3 KARBIT DAN FLY ASH SEBAGAI BAHAN CAMPURAN BETON SIAP PAKAI (BSP) (STUDI KASUS : PT. VARIA USAHA BETON)
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. C...

| Summary: | 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. CaO found on karbit waste it contained CaO approximately 56,5%. Method of concrete making and technical feasibility test on this research
use SNI standar (SNI 03-2834-2000). Environmental feasibility test use Toxicity Characteristic Leaching Procedur (TCLP) according PP No. 101 tahun 2014. The results of this research show that the use of karbit waste and fly ash can increase concrete power pressure at age of immersion 28 days. Concrete power pressure with 25% fly ash addition and carbide waste
2,5%;5%;10%; and 15% are 22,05 MPa, 19,43 MPa, 18,59 MPa, 16.09 MPa. Concrete power pressure increase 34,2%; 18,25%; dan 13,14%. Heavy metal concentration at concrete with fly
ash 25% and carbide waste 2,5% ; 5% ; 10% are below standard. The best composition is the mixing between 25% fly ash dan10% carbide waste which has Concrete power pressure 18,59
MPa. |
