Production of concretes using slag aggregates: Contribution of increasing the durability and sustainability of constructions

Case Studies in Construction Materials, 2021
The main by-product of the steel industry is slag. This paper investigates the use of slag aggregates of electric arc furnace (EAFS) and ladle furnace slag (LFS) in replacement of fine and coarse conventional limestone aggregates, for the production of ...

Can DNA from wet, temperate soils be used for palaeoecological reconstruction?

Journal of Quaternary Science, EarlyView.
ABSTRACT Sedimentary ancient DNA in well‐dated contexts (sedaDNA) has great potential as a palaeoecological proxy. A few studies have attempted palaeoecological reconstructions using sedaDNA from soil; these studies have been mainly restricted to cold and/or dry soils.

High‐Fidelity Synthetic Raman Spectra Generation for Sinter Basicity Prediction Using β$$ \beta $$‐Variational Autoencoders

Journal of Raman Spectroscopy, EarlyView.
A β$$ \beta $$‐variational autoencoder with β$$ \beta $$ = 0.1 generates high‐fidelity synthetic Raman spectra of industrial sinter with a 16‐fold improvement in spectral fidelity over SMOTE‐based augmentation (KL divergence: 0.0075 vs. 0.121), enabling reliable basicity prediction (R2 = 0.83) from limited labeled datasets.

Physical intrinsic characteristics of spheroidal particles in coal gasification fine slag

Green Processing and Synthesis
Spheroidal particles constitute the primary particulate signature within coal gasification fine slag (FS) residues. This research endeavor is centered on elucidating the physical configuration and intrinsic attributes of these spheroidal particles and ...

National Policy Coherence Counts for Reducing Inequality in Global Climate and Development Agendas

Sustainable Development, EarlyView.
ABSTRACT International institutions promote policy coherence as crucial to the effective and fair implementation of global sustainability agendas, though the evidence for its benefits is slim. We present here the first systematic cross‐country dataset on the consequences of national government efforts to promote policy coherence for vulnerable groups ...

Sustainable concrete production: Partial aggregate replacement with electric arc furnace slag

Journal of the Mechanical Behavior of Materials
The pursuit of sustainability in the construction industry has stimulated interest in seeking environmentally friendly alternatives to natural aggregates in concrete production. This study evaluates the behavior of concrete when electric arc furnace (EAF)

Relationship Between Micro‐Level Circular Economy and Sustainable Performance in the Metalworking Industry

Sustainable Development, EarlyView.
ABSTRACT The large multinational metalworking industry has increasingly adopted micro‐level circular economy (MLCE) practices; however, the extent to which these initiatives translate into sustainable performance remains insufficiently understood. This study examines the relationship between MLCE and economic, environmental, and social performance ...

HWTS 50 Tool Steel Tailored for Laser Powder Bed Fusion: Sliding Wear of Bare Surfaces and Nitriding Response in Comparison with 18Ni300 and AISI H13

steel research international, EarlyView.
This work investigates the wear resistance and nitriding behavior of PBF‐LB/M‐processed Osprey HWTS 50, a lean hot work tool steel. Three heat treatment conditions are compared to conventional wrought H13, H11, and PBF‐LB/M 18Ni300. The study highlights HWTS 50's enhanced nitrogen diffusion, deeper nitriding hardness depth, and comparable or improved ...
