Abstract
Concrete is the most broadly used material in construction worldwide. One of the type of concrete is reactive powder concrete with fibers that is a relatively new member of the hight strength concrete family. The object of adding fibers into cement-based materials to improve toughness, strain capacity and to reduce the tendency of crack propagation. In this work the critical parameters of fiber reinforcement reactive powder concrete such as modulus of rupture and toughness are investigated. The efficiency of fiber reinforcement depend upon the fibre length, the orientation of the fibers, and the fibers-matrix shear bond strength. The type of fibers used in this investigation are stainless steel, the volume of fibers are 1,5 % of the total volume and aspec ratio 75,100,125 with 0,2 mm in diameter. The investigation shows that fiber with aspec ration 100 results the best value of compressive strength, and fiber with aspec ratio 125 results the best value of modulus of rupture, toughness of the concrete.
