Structural Concrete, EarlyView.Abstract Fiber reinforced polymer (FRP) wrapping technology is commonly used to enhance the compressive strength (CS) of reinforced concrete (RC) members. Accurate prediction of the compressive strength of FRP‐confined concrete columns is crucial for optimizing structural design and helps reduce the time and costs associated with physical testing ...

Australian Endodontic Journal, EarlyView.ABSTRACT This study aimed to compare the physicochemical properties of EndoSequence Root Repair Material (ERRM) Fast and CeraPutty with ProRoot MTA and Biodentine, focusing on setting time, radiopacity, microhardness, and pH. Setting time was measured using a Gilmore‐type indenter applied every 5 min until no indentation was observed (n = 15 per group).

Archaeometry, EarlyView.ABSTRACT With this contribution, an attempt is being made to chart the timeline of the invention of the European hard‐paste porcelain based on historical documents. They were evaluated to trace the development lines from Tschirnhaus's early experiments with burning mirrors and lenses in the 1680s to finding ‘wax porcelain’ around 1694 to the ...

Contact point geometry governs structural buildup at rest in Portland cement–limestone blends
Journal of the American Ceramic Society, EarlyView.Abstract The early stiffening of fresh cement paste plays a key role in shaping and stability during casting and 3D printing. In Portland cement systems, this phenomenon arises from the formation of calcium–silicate–hydrate (C-S-H$\text{C-S-H}$), which stiffens grain‐to‐grain contacts.

Influence of attachment techniques on coral seeding unit deployment cost and performance
Restoration Ecology, EarlyView.Attachment of coral propagules to the reef surface is a bottleneck in the efficiency and efficacy of coral restoration techniques, with hypothesized tradeoffs between the relative investment in attachment (labor and materials costs) and propagule yield. Here we quantified the investment required and retention over 1 year for 11 coral seeding attachment
