Improving the flexural capacity of extrudable foamed concrete with glass-fiber bi-directional grid reinforcement: An experimental study

Composite structures, 2019
A wide experimental campaign of 40 three-point-bending tests on small-scale foamed concrete beams in the low-to-medium density range (400–800 kg/m3) is presented.

Tough, Ductile, and Strong Hard‐Soft Cementitious Composite Enabled by Multi‐Material Additive Manufacturing

Advanced Materials, EarlyView.
Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including

USE OF U-WRAP TO OVERCOME CONCRETE COVER DELAMINATION IN VARIOUS SIZES OF BEAMS USING STRUT AND TIE MODELLING [PDF]

Proceedings on Engineering Sciences
Reinforced concrete beams reinforced with Fiber Reinforced Polymer (FRP) have several failure patterns, one of which is Concrete Cover Delamination. To prevent this failure, in this study, FRP U-Wrap was installed which was calculated using Strut and Tie

Ammonium Salts as Curing Agents to Obtain Ionic Epoxy Resins With a Thermoplastic‐to‐Thermoset Transition

Advanced Materials, EarlyView.
Ionic epoxy networks are prepared using ammonium salts as hardeners, leading to a two‐stage curing process with a thermoplastic‐like intermediate. This uncommon behavior enables extrusion and fabrication of thermoplastic prepregs that can be cured into thermoset composites.
