possess pozzolanic property, Blast furnace slag ? DETERMINATION OF POZZOLANIC ACTIVITY • Pozzolanic activity is determined by “strength activity indexes” • Six mortar cubes are prepared (ASTM) →”Control Mixture” 500 g portland cement+1375 g sand+242 ml water →”Test Mixture” 400g of portland cement+100g of pozzolan+1375g of sand+some water for the same consistency, Compressive testing at 7 or 28 days • Strength Activity Index (SAI) =A/B*100 • A=f’c of test mixture • B=f’c of control mixture • ASTM C 618 → SAI ≥ 75%, CHEMICAL COMPOSITION OF POZZOLANS • Silica Fume is mostly SiO2 • G.
