Polypropylene Fibre-Reinforced Concrete - an overview ...

An optimum dosage of polypropylene fibre around 0.1–0.5% by volume of mix is recommended for concrete to obtain a proper high temperature resistance [134–136], and it is found that the resistance of polypropylene fibre reinforced concrete to high temperature increases with the increase of the length of the fibre [131].
