Sifat Mekanik Beton Geopolimer Abu Terbang Hybrid Dengan Pecampuran Portland …

The use of Portland Composite Cement (PCC) as a substitute material in fly ash geopolymer hybrid concrete will accelerate the geopolymer reaction since the geopolymer becomes more reactive. In this study, the fly ash geopolymer hybrid concrete used 12 M NaOH concentration, modulus of silicate (Ms) 2.5 and 15% PCC cement, and extra water 80 kg/m3. Tests of mechanical properties carried out were …
