Determination of Mechanical Properties of Steel Fiber Reinforced Concrete with Mineral Admixtures

This paper investigation on M-30 grade of concrete with water cement ratio 0.45 to study the compressive strength, and tensile strength of steel fibers reinforced concrete (SFRC) containing fibers of an interval of 0.5 %, 1 %, 1.5 % volume fraction of hook end steel fibers of aspect ratio 60 were used. The different percentage of one or more mineral admixtures with combination of steel fibers is used in this study. After curing this specimen were tested as per relevant codes of practice Bureau of Indian standard. A result data obtained has been analyzed as compared with a control specimen. A relationship between compressive strength VS. days and flexural strength VS days respected graphically. Result data clearly shows percentage increase in 7, 28 & 54 days compressive strength for M-30 grade of concrete.
