“…Because of their low stiffness, these fi bres are particularly effective in controlling the propagation of micro-cracks in the plastic stage of concrete. However, their contribution to post-cracking behaviour, unlike steel fi bres, is not known to be significant [18,19].…”

“…It is also important to have a combination of low and high modulus fi bres to arrest the micro-and macro-crack, respectively. Another benefi cial combination of fi bres is that long and short fi bres can control different scales of cracking [18,19]. The benefi cial effects of nonmetallic fi bres could be attributed to their high aspect ratios and increased fi bre availability at a given volume fraction.…”

“…Despite the benefi ts of fi bre reinforcement, fi bres can make cementitious materials diffi cult to work, in the fresh state, compromising hardened state properties [13]. The addition of fi bres at high dosages, however, has potential disadvantages in terms of poor workability and increased cost [18,19]. Micro-defects, such as voids, honeycombs and clumping or 'balling' of fi bres can be a problem at high fi bre contents [6].…”

“…Therefore, in recent years, chopped synthetic fibers, such as polyethylene (PE) (Wang, Le et al 2016), polyvinyl alcohol (PVA) (Sahmaran and Yaman 2007), polyethylene terephthalate (PET) (Foti 2011) and polypropylene (PP) have been added to concrete as reinforcement to enhance the mechanical and engineering properties of concrete. Mechanical properties of concrete, such as residual strength, tensile splitting strength, and flexural strength after heating may also change by including fibers (Peng, Yang et al 2006;Tanyildizi 2009) Micro-and macro-synthetic fibers deal with micro-and macro-cracks, respectively, and some research has been performed to introduce macro-synthetic fibers as a steel fiber-replacement in shotcrete and other structural applications (Oh, Park et al 2005;Oh, Kim et al 2007;Suji, Natesan et al 2007). Depending on their shape and geometry, the fibers are capable of considerably enhancing the ductility, impact resistance, fracture energy, fire resistance, and durability of concrete (Oh, Park et al 2005;Oh, Kim et al 2007).…”

Due to their low modulus of elasticity relative to that of steel fibers as well as their crimped shape, macro-synthetic (macropolymeric) fibers demonstrate higher deformation at Proc.…”

Abstract-Polypropylene is a thermoplastic polymer utilized as a part of wide assortment of uses including bundling, materials (e.g., ropes, warm clothing and covers). Polymer cement is a piece of gathering of cements that utilizes polymers to supplement bond as a cover. The sorts incorporate polymer-impregnated solid, polymer cement, and Polymer-Portland-bond concrete. The aim of the study was to achieve maximum strength of concrete by using optimum weight of polypropylene fibers. Fiber reinforced concrete is used in a variety of engineering applications because of its satisfactory and outstanding performance in the industry and construction field. Polypropylene fiber in concrete mix design is used for multiple purposes that includes rigid pavement, selfcompacting concrete and other applications. 40 cylinders of polypropylene concrete were casted and tested for 7 and 28 days' strength for both compressive and split tensile strength. It was concluded that the significant improvement was observed in ultimate compressive strength after 7 and 28 days. The optimum percentage of Polypropylene fiber was obtained to be 1.5 percent of cement by volume. The addition of small amount of polypropylene improved the mechanical properties of concrete.

With the increasing demand on structural toughness and energy absorption capacity, the addition of fiber to concrete has become an issue of significance. This paper studies the bond behavior of Basalt FRP (BFRP) minibar with straight, twisted and crimped geometric characteristics. The failure modes, pullout curves and bond strength were compared, and their interface degradation, damage evolution and failure mechanism between single fiber and concrete matrix were analyzed. Additionally, commercial steel fibers and polypropylene fibers were compared with the BFRP minibars to clarify the effect of fiber type on failure morphology, bond strength and interface properties. The results showed that the pulling out process for straight BFRP minibars, twisted BFRP minibars and crimped BFRP minibars was constituted by the elastic bonding stage, the partial de‐bonding stage, the complete de‐bonding stage and the pullout of fiber. The bond strength was composed of chemical adhesion and mechanical bond, where the mechanical bond play important role after the initial failure of chemical adhesion. The bond strength of crimped BFRP minibar, the hooked steel fiber, the indented polypropylene fibers and the twisted BFRP minibar were enhanced by 358%, 324%, 115%, and 54.5% compared to straight BFRP minibars. The interface bonding strengths improve with the increase of matrix strength. Dense microstructures of matrix improve the bond strength. The bond‐slip constitutive model was proposed for crimped, twisted and straight BFRP minibars with regression coefficient of 0.978, 0.891, and 0.992, respectively.Highlights Influence of fiber geometry and concrete strength on the pullout behavior Interface degradation, damage evolution and failure mechanism between minibar and concrete Bond‐slip constitutive model of straight, twisted and crimped BFRP minibars
