Structural Concrete, Volume 27, Issue 2, Page 1364-1382, April 2026.Abstract An analytical framework suited for the analysis of shear‐critical ultra‐high performance concrete (UHPC) members is presented. The numerical methodology utilizes a nonlinear finite element analysis formulation integrated with an artificial neural network (ANN) that characterizes the UHPC tension response based on its mix design. In addition, a

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 ...
