An Investigation of Steel Fiber Reinforced Concrete with Fly Ash

Abstract

-This paper deals with Investigation for M-25 grade of concrete having mix proportion 1:1.50:3.17 with water cement ratio 0.465 to study the compressive strength, and Flexural strength of steel fiber reinforced concrete (SFRC) containing fibers of an interval of 0.5% from 0.0% to 1.5% volume fraction of hook end Steel fibers of 71 aspect ratio were used. The percentage of Fly Ash by weight is to be increased by 10% from 00% to 30%. After curing these specimen were tested as per relevant codes of practice Bureau of Indian Standard. A result data obtained has been analyzed and compared with a control specimen. A relationship between Compressive strength vs. days, and flexural strength vs. days represented graphically. Result data clearly shows percentage increase in7, 28 & 45 days Compressive strength for M-25 Grade of Concrete.
