Fibre reinforced concrete with a combination of polyolefin ...

Jul 01, 2017  The hybrid fibre proportions added to the mix were chosen with the aim of achieving an improved polyolefin fibre reinforced concrete (PFRC) with a small quantity of steel fibres. In that sense, the smaller fraction volume explained above of 0.33% was chosen to evaluate the synergies when a fibre cocktail with a 0.49% volume fraction of ...

Polyolefin fiber-reinforced concrete enhanced with steel ...

Aug 01, 2014  This paper suggests that it could be possible to produce a hybrid fiber-reinforced concrete with a fiber cocktail made of steel-hooked fibers and macro polyolefin fibers with a bilinear fracture load–deflection behavior. The combination of the two types of anchorage chosen, it would seem, could offer a suitable joint action.
