Abstract

This research paper presents the effects of using supplementary cementitious materials in binary and ternary blends of concrete incorporating fly ash and silica fume. A total of 12 concrete mixtures were designed having a total binder content of 400 kg/m and water binder ratio of 0.4. Portland cement was replaced by fly ash at levels of 30%, 40% and 50%, silica fume at levels of 6% and 10% by weight. The compressive strength test were conducted on test specimens cured under different types of curing systems like accelerated curing, warm water curing along with normal curing were done and the results were compared. Based on the experimental results, polynomial regression models and coefficients were developed between standard compressive strength and early strength attained by accelerated curing and warm water curing at 28-90 days.
