Do PCEs Adsorb Preferentially on OPC or Calcined Clay?
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 ...

Life-cycle low-carbon design and assessment of UHPC beams integrating flexural capacity requirements
The excellent mechanical properties of ultra-high performance concrete (UHPC) will reduce the cross-sectional size of UHPC beams, resulting in a decrease in the amount of UHPC and the carbon emission.

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

Recent Advances in Carbon Materials for Cathodes and Interlayers in Lithium–Sulfur Batteries
This review examines dimensional carbon materials (0D–3D) as hosts and interlayers for Li–S batteries. It details how structural morphology, heteroatom doping, and catalytic functionalization effectively mitigate the polysulfide shuttle effect, manage volume expansion, and accelerate redox kinetics.

Existing methods often struggle to balance accuracy and robustness against complex interference such as noise and artefacts inherent in industrial CT imaging. To overcome these limitations, we propose an innovative framework named MultiBlock‐SwinUnet. This architecture is designed to enhance feature extraction for different categories of concrete and ...
