Mechanical Properties of Steel Fiber-Reinforced Concrete by Vibratory Mixing Technology

Advances in Civil Engineering, 2018
As a kind of important engineering material, steel fiber-reinforced concrete was used widely in civil engineering. Up to now, steel fiber-reinforced concrete was usually produced by the traditional mixing method. For the reason of uniform distribution of

The influence of fiber RC beams under flexure on the chloride-induced corrosion

Case Studies in Construction Materials, 2022
Corrosion of rebars is the main cause of the deterioration of reinforced concrete structures. In an aggressive marine environment, rebar corrosion occurs due to chloride ion penetration of the reinforced concrete (RC). This paper presents the findings of

Influence on compressive and tensile strength properties of fiber-reinforced concrete using polypropylene, jute, and coir fiber

Journal of the Mechanical Behavior of Materials, 2023
This research work is related to the use of environment friendly materials like fibers of coir, polypropylene and jute in concrete. An economical reinforced concrete is produced by reducing the diameter of steel bar by using fiber ropes. We have examined

Multiaxial compressive strength of hybrid fiber reinforced concrete: A unified empirical model

Frontiers in Materials, 2023
In engineering design, the strength analysis of concrete structures heavily depends on the compressive strength of hybrid fiber reinforced concrete (HFRC), which also has an impact on the stability and safety of the structure. The objective of this study

Compatibility of Methacrylate Based Resins Controls Interfacial Failure and Toughness in 3D‐Printed Multimaterial Composites

Advanced Engineering Materials, EarlyView.
This work shows that the mechanical performance of multimaterial digital light processing (DLP) printed thermoset composites is governed by resin compatibility and interfacial design rather than spatial patterning alone. Brittle and ductile resin combinations produced premature interfacial failure, while graded interfaces and mechanically compatible ...

Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

Advanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.
