Fatigue behaviour of a polymer concrete with and without added polyester fibre / Omar Bapokutty

The fatigue and fracture behavior of polymer concrete has been studied. The study has been conducted on polymer concrete plates with and without notch under fatigue loading of constant amplitude (Fa = 0.05 kN) and at frequency of 25 Hertz. The fatigue resistant of polymer concrete material reinforce...
