“…Zhang et al (2005) and Mohammadi et al (2009) found better crack resistance properties and enhanced energy absorbing capacity of HFRC composite structures against impact. On the basis of drop weight tests performed on steel-polypropylene HFRC, Komlos et al (1995) and Song et al (2005) reported positive role of polypropylene fibers in improving the impact resistance of HFRC. This improvement was mainly attributed to the increase the tensile strain capacity of the concrete in the plastic state due to the addition of polypropylene fibers.…”

This paper investigates the stress-strain characteristics of Hybrid fiber reinforced concrete (HFRC) composites under dynamic compression using Split Hopkinson Pressure Bar (SHPB) for strain rates in the range of 25 to 125 s -1 . Three types of fibers -hooked ended steel fibers, monofilament crimped polypropylene fibers and staple Kevlar fibers were used in the production of HFRC composites. The influence of different fibers in HFRC composites on the failure mode, dynamic increase factor (DIF) of strength, toughness and strain are also studied. Degree of fragmentation of HFRC composite specimens increases with increase in the strain rate. Although the use of high percentage of steel fibers leads to the best performance but among the hybrid fiber combinations studied, HFRC composites with relatively higher percentage of steel fibers and smaller percentage of polypropylene and Kevlar fibers seem to reflect the equally good synergistic effects of fibers under dynamic compression. A rate dependent analytical model is proposed for predicting complete stress-strain curves of HFRC composites. The model is based on a comprehensive fiber reinforcing index and complements well with the experimental results.

“…The synergistic effects in terms of first crack strength, failure strength and strength reliability of mono-fibre composites and hybrid fibre composites have been reported (Song, Wu, Hwang, & Sheu, 2005). The study revealed that Hybrid fibre composites showed larger scatter in percentage increase in the number of post crack blows as compared to mono-fibre composites.…”

Fibre reinforced concrete (FRC) presently utilized as a part of special structures subjected to dynamic loads for example airport pavements, expressways overlays, bridge decks and machine foundations. In most cases, FRC contains just a single kind of fibre. The utilization of at least two kinds of fibres in an appropriate mix can possibly improve the mechanical properties of concrete and result in performance synergy. The audit demonstrates that the blend of fibre allows a more powerful control of the dynamic crack development. This review analyses the components for synergistic impacts that gives direction on the fiber and matrix choice.

“…This is because the settlement and plastic shrinkage cracks may pass through fresh concrete, thus forming planes of weakness and lowering the integrity of the structure of concrete (Song et al, 2005). PP fibers mitigate plastic and early drying shrinkage by increasing the tensile property of concrete and bridging the forming cracks (Toutanji, 1999).…”

Durability of the concrete depends on the mass transfer properties of the concrete. This paper investigates the chloride diffusion in polymer-concrete composites subjected to pure diffusion process for 720 days. Chloride profiles for all types of concrete were obtained and then chloride diffusion coefficients were calculated. Extensive experimental program showed a significant enhancement of concrete durability by means of polymer-concrete composites. Reducing numbers and size of cracks and blocking the interconnected pores in concrete can enhance the durability of concrete. The results of this experimental study revealed that utilising both synthetic fibres and polymers in concrete improved durability of the concrete significantly.
