Hybrid NDT‐Machine Learning Framework With SHAP‐Based Interpretation for Predicting Compressive Strength of Steel Slag Concrete

Engineering Reports, Volume 8, Issue 4, April 2026.
This study proposes a hybrid non‐destructive testing (NDT) and machine learning framework to predict the compressive strength of steel slag concrete. The integration of UPV, Rebound Hammer, and mixture parameters with interpretable ANN modeling enables accurate, sustainable, and explainable strength assessment for in situ concrete evaluation.

Processing–Property Mapping of Flash‐Sintered Wall Tile Bodies

International Journal of Applied Ceramic Technology, Volume 23, Issue 2, April 2026.
ABSTRACT This study investigates the effects of furnace temperature (900°C and 945°C), applied electric field (50–200 V.cm−1), and current density (50–150 mA.mm−2) on the physical properties and microstructure of flash‐sintered wall tile bodies. Water absorption, bulk density, and open porosity were measured and compared with an industrially fired ...

In-situ early age hydration of cement-based materials by synchrotron X-ray powder diffraction [PDF]

, 2015
Cement based binders are building materials of worldwide importance. Since these samples are very complex, the knowledge/control of their mineralogical composition are essential to design and predict materials with specific/improved performance. Rietveld

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 ...

Non‐destructive and Destructive Structural Build‐Up of MgO–SiO2 Systems Enhanced by Hydration Agents

Journal of the American Ceramic Society, Volume 109, Issue 4, April 2026.
ABSTRACT This study investigated the effects of three hydration agents (HAs), Mg(CH3COO)2, MgCl2, and HCl, on the nondestructive and destructive structural build‐up of MgO‐SiO2 pastes through rheological characterization. Isothermal calorimetry, X‐ray diffraction (XRD), thermogravimetry/derivative thermogravimetry (TG‐DTG), scanning electron microscopy

Alkali-activated binders: a review: part 2. About materials and binders manufacture [PDF]

, 2008
This paper summarizes current knowledge about alkali-activated binders, by reviewing previously published work. As it is shown in Part 1, alkali-activated binders have emerged as an alternative to (ordinary Portland cement) OPC binders, which seem to ...

Circular Alkali‐Activated Cements Based on EAF Slags and Biomass Bottom Ash Using Rice Husk Ash–Derived Sodium Silicate

Journal of the American Ceramic Society, Volume 109, Issue 3, March 2026.
ABSTRACT This study investigates sodium silicate (SS) solutions derived from rice husk ash (RHA) dissolved in 8 M NaOH as sustainable activators for alkali‐activated cements (AACs), compared with commercial SS. AACs were produced using a 50:50 blend of electric arc furnace slag (EAFS) and biomass bottom ash (BA). The effects of NaOH/RHA ratio (6.6–2.8)
