The clashing of in situ and pre‐cast technologies—Western trends and local traditions in concrete engineering shaping shell construction in 20th‐century Hungary

open access: yesStructural Concrete, EarlyView.
Abstract After a blossoming pre‐World War II (WWII) period, the concrete construction industry in then‐socialist Hungary existed in a relative isolation from the Western World during the mid‐20th century. In this paper, we focus on the body of work of one of the then newly established state‐owned design offices, IPARTERV, to show how the isolation ...

Why did modern post-tensioned floors flourish in the us and not in europe -a matter of tradition? [PDF]

open access: yes, 2016
Unlike in Europe, prestressed concrete with post-tensioned reinforcement came to be a standard technique in building construction in the US. Kenneth Bondy has been the only one who has made a significant contribution to clarify why this occurred, by ...

Analysis of flow rates in cracked reinforced concrete

open access: yesStructural Concrete, EarlyView.
Abstract According to Eurocode 2, part 3, autogenous self‐healing of separation cracks with a width ≤0.20 mm can be considered under certain hydraulic conditions. However, practical experience shows that healing does not always reliably occur even when this crack width is maintained.

Experimental investigation on post‐installed anchorages with cast‐in anchor reinforcement under tension loading

open access: yesStructural Concrete, EarlyView.
Abstract Anchors are used to connect different structural and non‐structural components to reinforced concrete structures. Anchorages when subjected to tension loading might fail in different failure modes, with concrete cone breakout (CCB) being one of the most common.

Voraktivierung als Weg zur Anpassung der Kinetik Mechanochemischer Transformationen

open access: yesAngewandte Chemie, Volume 138, Issue 3, 16 January 2026.
Die Kinetik mechanochemischer Reaktionen kann durch die selektive Voraktivierung von Ausgangsreagenzien deutlich verändert werden, wie durch Reaktionsüberwachung mittels zeitaufgelöster in‐situ‐Pulver‐Röntgendiffraktometrie und ab initio‐Dichtefunktionaltheorie‐Simulation gezeigt wurde.
