Abstract. The use of fiber (steel or synthetic) reinforced concrete (FRC) had a considerable increase during the last decades mainly due to its higher resistance to crack formation and simplified casting technique. At the same time fiberconcrete strength properties are non-linear with a high scatter. The paper presents results for fiberconcrete post-cracking behavior control by means of fresh FRC flow numerical simulations and prediction of internal structure (fiber orientation and distribution) formation

Keywords: fiber reinforced concrete (FRC), crack forming, fiberconcrete strength, flow numerical simulation, internal structure .
