This paper determines the effect of discrete fibers on the elastic modulus of concrete and cement composites. Five types of discrete fibers consisting of steel, polypropylene, macro-polyolefin, polyvinyl alcohol (PVA), and basalt fibers were investigated. Results show that discrete fibers had little effect on elastic modulus for fiber-reinforced concrete (FRC) with coarse-to-fine aggregate ratio (C/S) greater than 1. However, for FRC with C/S smaller than 1 and fiber-reinforced cement composites (FRCCs), discrete fibers reduced the elastic modulus. Accordingly, a new elastic modulus equation is proposed to better estimate the elastic modulus of FRC with a maximum fiber volume fraction of 10%. The proposed equation was compared with existing equations from other codes, including American, Japanese, Korean, Norwegian, and European codes, as well as equations proposed by other researchers. These equations were evaluated using more than 400 data points taken from the experimental program and other literatures. The proposed equation provides the most accurate prediction for the elastic modulus of FRC and FRCC with a coefficient of variation of 15% as compared to 32% using ACI 318 equation for C/S ≤ 1.

“…Polyolefin chemical fibers demonstrate good performance in flexural fatigue strength, ductility toughness, and impact resistance [40][41]. Synthetic fibers have also been suggested as an alternative reinforcement material to steel fibers [42] in cementitious composites as it is non-corrosive, non-magnetic and do not result in hazardous protrusions [39].…”

RCC consumes large quantities of natural resources like gravel stone and steel, and there is a need to investigate on an innovative material that utilizes limited quantities of natural resources but should have good mechanical strength. This study deals with the experimental investigation of strength evaluation of cementitious composites reinforced with polyolefin fibers from 0% to 2.5% (with interval of 0.5%), namely Polyolefin Fiber Reinforced Cementitious Composites (PL-FRCC) and developing statistical regression models for compressive strength, splitting-tensile strength, flexural strength and impact strength of PL-FRCC. Paired ttests (for each PL fiber percentage 0 to 2.5%) bring out that there is significant difference in compressive and splitting-tensile strength when curing periods (3, 7, 28 days) are varied. Also, a strong relationship exists between the compressive and flexural strength of PL-FRCC. The proposed mathematical models developed in this study will be helpful to ascertain the mechanical strength of FRCC, especially, when the fiber reinforcing index is varied.

“…Although many researchers investigated the performance of HFRC through analytical modeling [30][31][32][33] which played a significant role in investigating the behavior of HFRC, but these researches could not fully explore the fundamental mechanism and performance under different loading conditions. Therefore, to overcome this deficiency of analytical modeling one can move toward the three-dimensional finite element modeling (FEM) which saves cost and time in comparison with experimental work and can investigate the complex damaging mechanisms of the concrete [34].…”

The modern research is aimed to enhance the tensile properties of concrete so that its performance should be made better in various reinforced concrete structures. In the current study, twenty hybrid-fiber-reinforced concrete (HFRC) columns and one plain concrete column were cast to examine the effect of hybrid fibers on the axial capacity, load-deflection response and cracking patterns of columns under axial concentric loading. All specimens were square in cross section having a side length of 150 mm and a height of 1200 mm. Two different types of fibers were used; one is steel fibers (SF) and second is polypropylene fibers (PPF). Four different volumetric ratios of SF (0.7%, 0.8%, 0.9%, 1.0%) and five different ratios of PPF (0.1%, 0.3%, 0.5%, 0.7%, 0.9%) were used in the current study. The results indicate that the combination of 0.8% SF and 0.5% PPF performed well for load-carrying capacity and a combination of 0.9% SF and 0.3% PPF presented the best performance for the ductility of HFRC columns. Moreover, a constitutive finite element model (FEM) was proposed using concrete damaged plastic (CDP) model in ABAQUS for predicting the axial behavior and crack patterns of HFRC columns under concentric loading. A close agreement was observed between the experimental measurements and FE predictions. Finally, a detailed comparison of theoretical axial capacities of HFRC columns was performed using the predictions of various codes and proposed equations.
