Numerical analysis of the effects of corrosion on the punching shear capacity of reinforced concrete flat slabs with openings

Structural Concrete, Volume 27, Issue 2, Page 1663-1683, April 2026.
Abstract The reinforcement corrosion is one of the main degradation mechanisms in reinforced concrete structures. Its effects can harm structural elements by reducing mechanical capacity, mainly due to diminished reinforcement properties and expansive reactions within the concrete.

Do PCEs Adsorb Preferentially on OPC or Calcined Clay?

Journal of the American Ceramic Society, Volume 109, Issue 4, April 2026.
ABSTRACT In multi‐component binders, admixtures such as polycarboxylates (PCEs) may exhibit preferential adsorption onto one component. Hence, for the first time PCE adsorption on ordinary Portland cement (OPC) and calcined clay (CC) in an OPC/CC blend was quantified by separating the OPC and CC particles from the hydrated cement employing a ...

Distributed AutoML framework for multi‐objective optimization of concrete crack segmentation models

Structural Concrete, Volume 27, Issue 1, Page 998-1019, February 2026.
Abstract Monitoring cracks in concrete surfaces is essential for structural safety. While machine vision techniques have received significant interest in this domain, selecting optimal models and tuning hyperparameters remain challenging. This paper proposes a Distributed Automated Machine Learning (AutoML) framework for efficiently designing and ...
