Influence of Polypropylene Fibres on Recycled Aggregate Concrete

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. In the present experimental study compressive, split and shear strengths were evaluated. The results showed that, the incorporation of PP fibers increases the strengths in RAC. Few Regression Models were deduced to estimate the strengths for RAC with respect to compressive strength.
