The Chemical Record, EarlyView.Geopolymers are presented as a chemically programmable platform whose properties emerge from activation chemistry, nanoscale disorder, and interfacial design. The review highlights sustainability challenges, the shift toward nanoengineered and hybrid systems, and the rise of halloysite‐based architectures enabling tunable structures across scales for ...

Mortars From Punic and Hellenistic–Roman Solunto: Materials, Formulations, and Technology
Archaeometry, EarlyView.ABSTRACT This study presents an archaeometric investigation of 18 hydraulic rendering and bedding mortars from Punic and Hellenistic–Roman Solunto (NW Sicily). The research aimed to characterize raw materials, reconstruct manufacturing sequences, and evaluate technological proficiency through mineralogical and petrochemical analyses.

Influence of cracks on concrete carbonation resistance [PDF]
, 2020 In reinforced concrete (RC) structures carbonation induced corrosion is one of the biggest durability issue. There are many factors that affect carbonation process (CO2 concentration, relative humidity, temperature, curing conditions and concrete ...

Carbonation of Demolished Concrete
, 2023 This study investigates the carbonation process in concrete, where carbon dioxide is naturally absorbed by the concrete over time. Crushing the concrete into smaller fractions has the potential to accelerate this process.

Boreas, EarlyView.Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...

An Updated Classification of Hydraulic Cements Used in Dentistry
International Endodontic Journal, EarlyView.ABSTRACT Mineral trioxide aggregate (MTA) was the first hydraulic cement used in endodontics. It is composed of Portland cement, a binder in concrete, and bismuth oxide to enhance the radiopacity. MTA was introduced in dentistry to be used as a root‐end filling material and also to repair root perforations.

The Front‐End of Circular Innovation in Incumbent Firms
Journal of Product Innovation Management, EarlyView.ABSTRACT The Circular Economy introduces ambiguity and complexity when developing products and services, by using materials and resources differently; innovations and related business models thus deviate markedly from those evident in the “linear economy”.

Effect of carbonation on high-slag binders
Cement production results in the significant release of CO2 into the environment. Therefore, the partial substitution of cement with supplementary cementitious materials (SCMs) is a primary strategy to reduce the upfront embodied carbon of concrete ...

Journal of Animal Physiology and Animal Nutrition, EarlyView.ABSTRACT Over recent years the use of yeast in feedstuffs has gained momentum due to novel developments in single‐cell proteins (SCPs). SCPs are considered a sustainable protein source, as their production enable to convert low‐value substrates (including industrial/agricultural wastes) into feed, with a related reduced environmental impact.
