Stone‐Cutting Dust as a Sustainable Supplementary Cementitious Material: A Comprehensive Review of Its Physicochemical and Mechanical Effects

Journal of Chemistry, Volume 2026, Issue 1, 2026.
Ordinary Portland cement (OPC) remains the most common binder used in construction and accounts for nearly 7%‐8% of the world’s CO2 emissions due to calcination of limestone and high energy use during clinker production. Reducing OPC content using SCMs is one of the major strategies to achieve sustainable construction.

Fatigue crack behaviour: comparing three-point bend test and wedge splitting test data on vibrated concrete using Paris' law

Fracture and Structural Integrity, 2016
The fatigue behaviour of concrete has become more important for the design of constructions due to the desire to build slimmer structures, which are more sensitive to fatigue loading.

Fast camera imaging of plasmas in Alcator C-Mod and W7-X

Nuclear Materials and Energy, 2018
In this work we present an analysis of fast-camera imaging of Alcator C-Mod's divertor region and of the plasma cross section in the W7-X stellarator. In C-Mod, the dynamics of intermittent edge plasma filaments are imaged at 397,100 frames per second in

Phase‐Field Modeling for Failure Behavior of Polymer Fiber‐Reinforced High‐Performance Concrete Using the Schapery Viscoelastic Model

Proceedings in Applied Mathematics and Mechanics, Volume 25, Issue 4, December 2025.
ABSTRACT Concretes and cement‐based materials are known to exhibit brittle failure, which limits their structural performance after cracking. To overcome this, fiber reinforcement is commonly used to enhance the post‐cracking properties of the material.

Scientific Opinion on the criteria to be used for safety evaluation of a mechanical recycling process to produce recycled PET intended to be used for manufacture of materials and articles in contact with food

EFSA Journal, 2011
This scientific opinion of EFSA deals with the criteria to be used for safety evaluation of a recycling process to produce recycled PET intended to be used for manufacture of materials and articles in contact with food. The principle of the evaluation is

Initial conditions for globular clusters and assembly of the old globular cluster population of the Milky Way

, 2010
Comparing N-body calculations that include primordial residual-gas expulsion with the observed properties of 20 Galactic globular clusters (GCs) for which the stellar mass function (MF) has been measured, we constrain the time-scale over which the gas of

Hypotese verifisering av tilslagstype innflytelse på CMOD av fiber betong.

, 2023
Tilsetting av fiber i betong har vært noe som lenge har vært benyttet for å tilføre strekkegneskaper i betongen og hindre blant annet riss i betongen. Det har i de siste årene vært et ønske om å undersøke om det er forsvarlig å bruke fiber betong i bærende konstruksjoner, og ikke kun i fundamenter og sprøytebetong som fiber har normalt sett vært ...

Fast imaging of filaments in the X-point region of Alcator C-Mod

Nuclear Materials and Energy, 2017
A rich variety of field-aligned fluctuations has been revealed using fast imaging of Dα emission from Alcator C-Mod's lower X-point region. Field-aligned filamentary fluctuations are observed along the inner divertor leg, within the Private-Flux-Zone ...
