Influence of natural fibers on physical, mechanical, and fire‐resistant properties of microconcrete

Structural Concrete, EarlyView.
Abstract This study examined the influence of natural fibers on the physical, mechanical, and fire‐resistant properties of microconcrete, in comparison with conventional polypropylene fibers used in cement composites. The fibers were characterized by FTIR and TGA/DSC to assess their composition and thermal stability, and FTIR was also performed after ...

Exploring the potential of Textile Reinforced Concrete for corrosion‐insensitive retaining walls

Structural Concrete, EarlyView.
Abstract In a context where durability concerns, particularly the corrosion of steel reinforcement, remain a critical challenge for conventional reinforced concrete structures under severe exposure, Textile Reinforced Concrete (TRC) is emerging as a promising alternative.

Seismic evaluation of the southbound Stellenberg Interchange Bridge, B5593, in South Africa

Structural Concrete, EarlyView.
Abstract This study presents a nonlinear finite element assessment of the seismic vulnerability of Bridge B5593, located in the south‐western region of South Africa. Previous evaluations identified a high likelihood of column failure; however, these were based on linear material models incapable of capturing damage evolution.

The challenges of GFRP RC beam design for limit states

Structural Concrete, EarlyView.
Abstract Glass fiber reinforced polymer (GFRP) bars are used ever more frequently in concrete construction due to their non‐corrosive and anti‐magnetic properties. Their research over the past decades focused on fundamental questions, such as the design aspects of beams under flexural loads.

Structural behavior of small square steel tubes reinforced self‐compacting concrete columns under biaxial eccentric loads

Structural Concrete, EarlyView.
Abstract In this study, the structural behavior of small square steel tube‐reinforced self‐compacting concrete (SSTR‐SCC) columns is investigated under symmetric and asymmetric biaxial eccentric loads. Twelve specimens were cast and tested under biaxial eccentric loads.

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 ...

Nomenclature on Immune‐Mediated Drug Reactions: An EAACI Position Paper

Allergy, EarlyView.
ABSTRACT Over the past several decades, there have been significant advances in our understanding of both immunological and pharmacological mechanisms of adverse drug reactions (ADRs). Immune‐mediated drug reactions (IMDRs) represent a small proportion of ADRs and are caused by a pathological activation of the immune system or inflammatory pathways ...

Flexural and shear strengthening of reinforced concrete elements

, 2013
This work focuses on research carried out on the use of the near surface mounted (NSM) technique to increase the flexural capacity of statically indeterminate reinforced concrete (RC) slabs or shallow beams, and the use of embedded through-section (ETS) bars for shear strengthening of these structures.

Ethylenediaminetetraacetic Acid and Other Dentine Bioactive Molecule‐Releasing Agents for Regenerative Endodontic Procedures: A Systematic Review

International Endodontic Journal, EarlyView.
ABSTRACT Background The bioactive molecules released from dentine are key to stem‐cell recruitment, proliferation and differentiation in regenerative endodontics. However, there is limited and conflicting information regarding current and potential agents for releasing dentine bioactive molecules for regenerative endodontic procedures.
