Polypropylene fiber reinforced concrete in railway crossties
Cracking of concrete crossties is a performance problem that reduces service life and increases maintenance costs. While strong in compression, plain concrete is relatively weak and brittle under tensile stresses. Inclusion of synthetic polypropylene macro fibers in concrete is known to improve …

Impact resistance of high strength fiber reinforced concrete
Concrete structures may be subjected to dynamic loading during their service life. Understanding the dynamic properties of concrete structures is becoming critical because of the increased concern about the dynamic loading of both civilian and military structures, and especially, the recent …

Sustainable bacteria-based self-healing fiber reinforced concrete
Self-healing concrete presents an innovative and eco-friendly solution with the potential to reduce maintenance costs through self-activated crack repair. This study examined the effect of varying bacterial content across different environmental conditions. Additionally, the coupling effect between …

Strength and Performance of Fiber-Reinforced Concrete Composite Slabs
… flexural toughness and first-crack strength of fiber-reinforced concrete using ASTM C1018 (1998) standard test. The performance of the specimens reinforced with fibers are compared with that of the specimens reinforced with welded-wire fabric (WWF), with the purpose of determining if …

Structural Behaviour of Self Consolidating Steel Fiber Reinforced Concrete Beams
… to a combination of moment and shear force, a reinforced concrete (RC) beam with either little or no transverse reinforcement can fail in shear before reaching its full flexural strength. This type of failure is sudden in nature and usually disastrous because it does not give sufficient warning …

Low-Shrinkage Fiber-Reinforced Concrete for Infrastructure Construction and Rehabilitation
… two classes of low-shrinkage high-performance concrete (HPC): fiber-reinforced super workable concrete (FR-SWC) for infrastructure construction and fiber-reinforced self-consolidating concrete (FR-SCC) for repair applications. HPC with excess content of shrinkage mitigation materials (SMMs), …

Shear performance and behavior of long carbon fiber reinforced concrete
… to investigate the shear performance of fiber reinforced concrete beams. Long carbon fibers, to be included with a traditional fresh concrete mix, were developed and their shear performance was evaluated and compared to the performance and behavior of unreinforced concrete, traditionally …

Machine Learning Prediction of Shear Capacity of Steel Fiber Reinforced Concrete
The use of steel fibers for concrete reinforcement has been growing in recent years owing to the improved shear strength and post-cracking toughness imparted by fiber inclusion. Yet, there is still lack of design provisions for steel fiber-reinforced concrete (SFRC) in building codes. This is …

Nondestructive characterization methods for quality control of steel fiber reinforced concrete
Pacadar is a precast concrete company, headquartered in Madrid, Spain, that had proposed a research project to the University of Illinois based on their need to nondestructively characterize steel fiber dispersion and orientation within concrete wind-tower elements in order to ensure adequate …

Strength and Performance of Steel Fiber Reinforced Concrete Post-Tensioned Flat Plates
… was performed on a one-third scale model steel fiber reinforced concrete post-tensioned flat plate. The specimen had nine 10ft x 10ft x 3in. bays along with a 2ft-6in. overhang. Distributed loading was applied with a whiffle tree loading system at each bay and overhang section. Throughout the …

Study of Mechanical Properties of PVA Fiber-Reinforced Concrete With Raman Spectroscopic Analysis
<p>The brittleness of concrete has always been a safety and economic issue of great concern. The low tensile strength of concrete is the cause of its intrinsic brittle nature. This is critical considering the amount of concrete used for the construction of highways, buildings, and other facilities. …

Numerical analyses of long carbon fiber reinforced concrete panels exposed to dynamic loading
… impact and blast performance of long carbon fiber reinforced concrete experimentally and numerically. Experimental tests were conducted on plain concrete (PC), reinforced concrete, and four different types of long carbon fiber reinforced concrete (LCFRC). The results from each test were then …

Fiber Orientation Effects on the Fracture and Flexural Toughness of Extruded Fiber Reinforced Concrete for Additive Manufacturing
In this study, the mechanical properties of a fiber-reinforced cementitious composite (FRCC) were derived for specimens fabricated using two different methods of casting: conventional cast construction and pump-driven extrusion. Through the extrusion process, fibers are more likely to be oriented …
