Mechanical Properties of Concrete after Addition of Different Types of Steel Fibres

ABSTRACT In this project effect of steel fibers on the strength of concrete for M 40 grade will be studied by varying the percentage of fibers in concrete and types of fibers. Compressive strength, Split Tensile Strength & Flexural strength will be compared and tabulated. Fibers addition to concrete results in more closely spaced and improved resistance to the cracks. Improvement observed in mechanical properties of controlled concrete due to present of steel fibers. There is a significant increase in Compressive Strength of concrete with addition of Crimped Steel Fiber when compared to Straight and Hooked Steel Fiber. The percentage increase in Compressive Strengths of Straight Steel Fiber (2%), Hooked Steel Fiber (2%) and Crimped Steel Fiber (2%) are 9.84%, 5.9% & 16.92% respectively. Similar trend is followed for other mechanical properties.
