Sažetak
In this study the pozzolanic activity of aluminosilicate materials (waste container glass, natural zeolite and waste building brick) with particles size <125 μm was tested using Frattini test and saturated lime test. For Frattini test three samples were prepared with Portland cement/pozzolan ratio 80:20. Samples were thermostated for 8 days at 40 o C. For saturated lime test 12 samples were prepared. The samples contained 1g of puccolan and 75 mL of saturated lime solution (2g Ca(OH) 2 in 1L of demineralised water). Samples were thermostated for 1, 3, 7 and 28 days at 40 o C. After each period of hydration, samples were filtered through Büchner's funnel using a vacuum pump and liquid phase was separated from the solid phase. Total alkalinity and CaO concentration in aqueous solutions were determined by titration with HCl and EDTA. The results showed that waste container glass, natural zeolite and waste brick of particles size <125 μm are pozzolanic active materials and they can be use as supplementary cementitious materials. The results did not confirm the correlation between the Frattini test and saturated lime test.
