摘要: This paper presents an experimental investigation on the effect of Nano Silica (NS) compressive strength concrete made with different cement contents. Two percentages NS, 1.5% and 3%, as partial replacement were investigated at contents 300, 400, 500 600 kg/m3. The NS testing ages 7, 28 56 days was evaluated. water absorption percentage (WA%) also investigated. content ratios 7 to that found correlated. effects enhancement WA% evaluated addition enhanced reduced WA%. maximum in recorded 1.5 % NS. As this ratio increased decreased but a values not less than mix without
