Influence of Polypropylene Fibres on Recycled Aggregate ...

2018-1-1  Abstract. This article presents the behavior of Recycle Aggregate Concrete (RAC) with and without addition of Polypropylene (PP) fibers. The natural coarse aggregate was replaced by recycle aggregate in the proportion of 0, 25, 50, 75 and 100%. The Polypropylene fibres (PP) were used in the recycle aggregate concrete by 1 and 2% by volume.
