Fracture behavior of polymeric fiber reinforced lightweight structural concrete

Fracture behavior of polymeric fiber reinforced lightweight structural concrete

A study has been made of the effect of short randomly dispersed polypropylene fibers on the fracture behavior of lightweight structural concrete. Using unnotched and precracked beams subjected to bend loading, it was possible to determine the toughness factor TF and to estimate specific J integral p...
