Development of Mechanical Properties of Steel Fibers Reinforced High Strength Concrete

This article deals with time development of basic mechanical properties of steel fibers reinforced high strength concrete (FRHSC). The basic mechanical properties were studied at different age of the fiber reinforced high strength concrete, exactly at the age 12, 15, 18 and 21 hours and 1, 2, 3, 7, 14, 21 and 28 days. The compressive strength was determined by using cubic specimens (100 x 100 x 100 mm). The tensile strength in bending and fragment compressive strength after bending were determined by prismatic specimens (40 x 40 x 160 mm). Bulk density were determined too. The comparison of mechanical properties of fibers reinforced high strength concrete and high strength concrete is in conclusion of this article.
