摘要: This work is focused on the mechanical properties of ternary blended nanoconcrete replacing cement with fly ash and nanosilica in optimized percentage. Ternary mix designed 0.45 water-to-binder ratio 438 kg/m3 cementitious content all mixtures a combination various percentages 40% by weight cement. The like compressive, split tensile flexural strength tests at age 7, 14 28 days are performed. With addition nanosilica, enhancement was observed properties, but when dosage more than optimum, bleeding as well segregation concrete observed. Response surface method used predicting values compressive this work, which found to be agreement experimental observations least 95% confidence levels.
