Abstract:
The benefits of fiber reinforced concrete (FRC) have been thoroughly investigated. Much of this work has focused on polypropylene FRC notched beams. Data on the bending behavior of beams with side notch is scarce. A pilot investigation on the compressive behavior of macro-synthetic FRC and on the splitting tensile strength of FRC was carried out. Twenty beam specimens with two different strength of 35 and 60 MPa was tested. The beams dimensions were 15*15*55 centimeter and they were notched at the bottom at mid and side span. Two different notch depth of 5 and 7.5 centimeter was implemented. At the end it was found out addition of fiber decreases compressive strength of 35 Mega Pascal concrete by about ten percent and it also decreases splitting tensile strength. Macro polypropylene fibers, which had 49 millimeter in length, increased bending peak load of beam specimens by ten and in some cases by about thirty percent. In some cases, addition of fiber decreased the load by thirteen percent
