Abstract

The purpose of this experimental investigation is to study the behavior of Concrete using Various fineness Fly ash. In this investigation was manufactured by usual ingredients such as cement, fine aggregate, coarse aggregate, water and mineral admixtures such as Fly ash at various replacement levels. The water binder ratio (w/b) adopted is 0.45. The concrete used in this investigation was proportioned to various target a mean strength of 20MPa, 25MPa, 30MPa. Specimens such as cubes, were cast and tested for various mixes are cast with 0%, 12.5%, 25%, and 37.5% replacement of various fineness Fly ash to study the mechanical properties such as compressive strength at different ages of concrete such as 7, 28, and 90 days. The mix Design as per IS 10262-1982.
