In Situ Curing‐Enabled 3D Printing of Continuous Fiber‐Reinforced Thermosetting Composites

Journal of Polymer Science, EarlyView.
In situ curing‐enabled the 3D printing of continuous fiber/thermoset composites, which were reviewed. Particularly, four types of in situ curing, were discussed, including Radiation‐induced curing, photothermal curing, electrothermal curing, and frontal polymerization. AI‐integrated printing was also analyzed.

Circular Economy Pathways for End‐of‐Life Wind Turbine Blades and Their Environmental Implications and Potential Urban Applications

Sustainable Development, EarlyView.
ABSTRACT The rapid expansion of renewable energy, particularly wind power, is expected to generate large volumes of composite waste from end‐of‐life (EoL) turbine blades in the coming decades. Managing this material represents a significant environmental and logistical challenge worldwide.

Colloidal Behavior of Carbonate Particles Microbially Precipitated in Microfluidic Droplets

Small, EarlyView.
In Microbially Induced Calcium Carbonate Precipitation (MICP), ureolytic bacteria trigger calcium carbonate precipitation via pH‐increasing urea hydrolysis. This enzymatically driven reaction induces the colloidal assembly of bacteria and carbonate particles into fractal networks.

Enhancing hydrophobicity and corrosion resistance of epoxy resin coatings using KH570-ZrO2 nanoparticles

Polymer Testing
Epoxy resin has excellent adhesion, mechanical strength, environmental adaptability and corrosion resistance. As a concrete coating, it can effectively seal internal pores, prevent the penetration of water and corrosive ions. However, the epoxy resin has

Sensitivity study on accuracy and relevant parameters in numerical modeling of internal tendon breaks

Structural Concrete, EarlyView.
Abstract This study investigates the numerical modeling of internal tendon breaks in prestressed concrete structures and evaluates the key parameters affecting accuracy. A combined approach is followed, involving global sensitivity analysis via the Elementary Effects Method and subsequent model calibration using experimental data from distributed fiber‐

Adhesion between high-strength concrete, epoxy resin and CFRP

, 2008
This paper presents a study on the adhesion between high-strength concrete, epoxy resin and CFRP. The adhesion of the high-strength concrete was compared with the same property measured in conventional concrete.

Pullout performance of steel bars partially bonded in concrete with epoxy resin

Revista IBRACON de Estruturas e Materiais, 2018
The installation of new reinforcing bars onto an existing structure is a common practice in civil construction both for old and new structures. The use of anchors has been extensively studied and normalized.

Bond, tension‐stiffening, and cracking in multi‐generational recycled aggregate concrete subjected to shrinkage strains

Structural Concrete, EarlyView.
Abstract The concrete industry is responsible for a significant portion of global waste production and multi‐generation recycled aggregate concrete (MGRAC) is a means to allow the sector to transition to a circular economy framework. To predict the behavior of MGRAC at the member level there is a need to understand the underlying mechanics of bond ...
