Abstract – HVFAC has excellent workability, low heat of hydration, adequate early-age and high later-age strengths, reduced drying shrinkage, reduced micro cracking, excellent durability characteristics while being more economical and environment-friendly when compared to conventional concrete. At high levels problems may be encountered with extended set times and slow strength development, leading to low early-age strengths and delays in the rate of construction. These drawbacks are overcome by using fibers. The present technology of making flexible pavements is increasingly becoming unsustainable because of rising life cycle costs and could be suitably replaced with high volume fly ash based concrete. This paper is a study of the behavior of high volume fly ash concrete which contains more than 50percentage of fly ash content. The different percentage replacement of fly ash includes 60percentage, 65percentage and 70percentage in addition with and without steel fiber for each percentage.
