On explicit modeling of polypropylene fiber effects on hydro-thermal behavior of heated concrete

This work focuses on the evaluation of the probability of percolation of polypropylene fibers (PPF) in creating a permeable network within heated concreted due to temperature induced degradation of fibers. Therefore, the intrinsic permeability supply of heated concrete containing PPF is accordingly estimated by a homogenization technique applied to the 3D heterogeneous microstructure
