Effect of polypropylene fibers on self-healing and dynamic modulus of elasticity recovery of fiber reinforced concrete
This study aims to evaluate self-healing properties and recovered dynamic moduli of
engineered polypropylene fiber reinforced concrete using non-destructive resonant
frequency testing. Two types of polypropylene fibers (0.3% micro and 0.6% macro) and two
curing conditions have been investigated: Water curing (at~ 25 Celsius) and air curing. The
Impact Resonance Method (IRM) has been conducted in both transverse and longitudinal
modes on concrete cylinders prior/post crack induction and post healing of cracks …
