Abstract

The use of fly ash in concrete today is an important subject and is growing in importance day by day. Using fly ash in concrete may provide both economical advantages and better properties in the production of concrete. Besides, concretes produced with different replacement ratios of fly ash is better than concrete to which other different types of fibers are added. This paper reports on the strength of concrete containing fly ash and various types of fibers like polypropylene fiber, glass fiber and steel fiber. The fly ash content used in this study was 0%, 10%, and 20% in mass basis; the fiber content was 0%, 0.5%, 1.0% and 2.0% in volume basis. The modulus of elasticity based on stress-strain curve was determined for fly ash based fiber reinforced concrete. According to the results of the study, addition of fly ash and fibers improves concrete strength based on the modulus of elasticity values obtained.
