A Termite‐Inspired Alternative to Cement

Advanced Functional Materials, Volume 36, Issue 27, 2 April 2026.
A termite‐inspired composite of clay, cellulose, and lignin forms a dense fibrous network with concrete‐like strength (32 MPa) and superior elasticity, processed at ambient temperature. Abstract Clay combined with organic materials is used by termites as a strong and durable construction material for their mounds with minimal environmental impact. Here,

Modeling the response of UHPC shear‐critical beams: Integrating nonlinear finite element analysis and artificial neural network

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

Guidelines for UHPC Materials

Journal of Asian Concrete Federation
As UHPC exhibited ultra-high strength, good toughness, and superior durability that can be intended for use in precast/cast-in-situ structures, precast structure elements, and repairs for buildings and civil engineering structures and non-structural elements, the guidelines cover the following aspects: (1) Definitions of the terminology ...

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.

Numerical study on dynamic response of a novel ribbed thin-walled UHPC box-type utility tunnel under gas explosion

Case Studies in Construction Materials
At present, RC utility tunnels are widely used in urban utility tunnels. As a typical confined space, the complex load effect generated by the internal gas explosion of the gas tank of utility tunnel may lead to local damage or overall destruction of the

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 ...
