Abstract/Summary
The study determined the effect of polypropylene waste fibers on the flexural strength of concrete by comparing the 28-day flexural strengths of plain concrete and polypropylene waste fiber-reinforced concrete. The modulus of rupture or flexural strength of concrete was determined by subjecting beam specimens under third-point loading. The study also determined the effect of polypropylene waste fibers on the impact strength of cement mortar by comparing the 28-day impact strengths of plain cement mortar and polypropylene waste fiber-reinforced cement mortar. The impact strength or resistance of concrete to impact loading was determined by subjecting tile specimens under an improvised drop-weight test.
The study had the following results:
a) The comparative analysis between the 28-day flexural strength of plain concrete and polypropylene waste fiber-reinforced concrete showed that an addition of polypropylene waste fiber between the range of 1.64% and 2.56% waste fiber content by volume in concrete can result in an increase in its flexural strength. The flexural strength of concrete at the specific range of the waste fiber content in percent by volume was found to have increased by as much as 3.28%. b) The addition of polypropylene fiber in cement mortar was effective in resisting the cracks induced by impact loading as the number of blows before failure were greater in waster fiber-reinforced mortar compared with plain mortar. c) The addition of polypropylene waste fiber to concrete was found to have the highest increase in flexural strength at the waste fiber content of 2.0% by volume while the resistance to impact loading was greatly effective at the waste fiber content of 2.25% by volume.
