CiteSeerX — Influence of Polymer Fiber on Strength of Concrete

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): This paper outlines an experimental study that measures the effects of polymer fiber on proprieties of concrete. However, polymer fiber may serve as a superplasticizer admixture which may result to concrete’s lower rate of water absorption, high-range water reducer, greater strength and excellent in elasticity.

Therefore, the use of different fibers in the concrete mixture is considered as an appropriate solution to eliminate these defects. In this experimental study, two types of polymer fibers, including simple polypropylene and ۴-element polyolefin hybrid fibers, were used to manufacture fiber reinforced geopolymer concrete specimens.

Effects of Polypropylene Fibers on the Physical and

The viability of using polypropylene fibers (PPF) in concrete was largely studied. Yet, few of the existing research studies investigated the effects of PPF on the properties of concrete containing recycled concrete aggregate (RCA). Mixes with different RCA replacement ratios and different PPF content were designed and tested. The test results showed that the addition of PPF did not change

Everything You Need To Know About Polypropylene (PP) Plastic

Polypropylene (PP) is a thermoplastic "addition polymer" made from the combination of propylene monomers. Natta perfected and synthesized the first polypropylene resin in Spain in 1954, and the ability of polypropylene to crystallize created a lot of excitement.

Addition of steel fibres to concrete is known to have a significant positive influence on the mechanical properties of concrete. Micro polypropylene (PP) fibres are added to concrete to improve its performance under thermal loads such as in case of fire by preventing the phenomena of explosive spalling. An optimum mixture of steel and micro PP fibres added to concrete may be utilized to

Polypropylene Fiber Reinforced Concrete : An Overview

Polypropylene fibers reduce the plastic shrinkage crack area due to their flexibility and ability to conform to form. The addition of 0.1% by volume of fibers is found effective in reducing the extent of cracking by a factor of 5-10. The extent of crack reduction is proportional to the fiber content in the concrete.
