Abstract:
Conventional concrete is commonly known as one of the brittle construction materials with poor tensilestrength. However the incorporation of various types of fibers specially steel fibers in concrete cansignificantly improve its strength and ductility, and limit crack propagation. In addition, it seems that magneticfield can affect mechanical properties of concrete containing ferromagnetic particles. The main objective ofthis study was to investigate compressive strength of steel fiber-reinforced concrete with the volume fractionsof 0.4, 0.7 and 1 percent under the influence of magnetic field. To achieve this goal, compressive strength testwas conducted on cube concrete specimens at the ages of 7 and 28 days. The experimental resultsdemonstrated that magnetic field increases compressive strength of fiber concrete with the volume fractions of0.4, 0.7 and 1 percent about 11, 13 and 13 percent at the age of 7 days, respectively. These amounts wereobtained for concrete specimens at the age of 28 days about 11, 17 and 12 percent, respectively.
