Fiber Orientation Effects on the Fracture and Flexural Toughness of Extruded Fiber Reinforced Concrete for Additive Manufacturing
… alcohol (PVA) fiber reinforcement by volume. The flexural properties of FRCC were determined using four-point bend tests according to a modified ASTM C1609. Calculations included the modulus of rupture (MOR) and flexural toughness based on load-deflection curves. The fracture properties of FRCC …

Strength and Performance of Fiber-Reinforced Concrete Composite Slabs
… strength due to a concentrated load, and the 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), …

Characterization and performance of eco and crack-free high-performance concrete for sustainable infrastructure
… steel fibers developed significantly higher flexural toughness compared to the reference concrete used for bridge applications. In parallel, autogenous crack healing capability of concrete equivalent mortar mixtures was monitored using microwave reflectometry nondestructive testing technique. …

Engineering properties of ring shaped polytheylene terephthalate (RPET) fiber self-compacting concrete
… as well as through compressive, tensile, and toughness strength tests. A water–binder ratio of 0.55 and working ranges from 0.25% to 1% of fiber content are successfully accepted for all sizes of RPET fibers. Result of the pullout test shows that RPET fiber interfacial bond strength ranges …

Performance and Design of Extruded Fiber-Reinforced Mortar with Preferentially Aligned Fibers
… concrete (FRC), focusing on fracture and flexural toughness properties, the impact of fiber orientation and distribution, and the evaluation of flexural models for predicting the behavior of functionally graded FRC. It embarks on a critical investigation aimed at bridging a significant gap …

Development, application and early-age monitoring of fiber-reinforced ‘crack-free’ cement-based overlays
… proposed to correlate early-age shrinkage and flexural toughness of cellulose fibers. In both models, a reasonable correlation with the test data was observed. In addition, factorial design method was used and a mathematical model was proposed to correlate different variables such as w/c, s/c, …

Valorisation of wind turbine blades into concrete : a contribution towards a more sustainable approach
… characterized for their compressive strength and flexural capacity. Results show that the form of DWTB-GFRP (as a powder, aggregate, or fiber) significantly impacts the properties of resulting concretes. Thus, while DWTB-GFRP powder leads to a substantial increase in the setting time (owing to the …
