Polymaterial Lattice Discrete Particle Model for the Optimization of Lightweight Aggregate Concrete: Intragranular Fracture and Compression Behavior

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 12, Page 4764-4779, 25 August 2026.
ABSTRACT Lightweight aggregate concrete (LWAC) offers clear advantages for sustainable construction, including reduced density and improved thermal insulation. However, its mechanical and fracture behavior is difficult to characterize due to the heterogeneity and brittle crushing of porous lightweight aggregates.

Computational intelligence model for predicting the compressive strength of FRP‐confined concrete column

Structural Concrete, Volume 27, Issue 3, Page 4398-4415, June 2026.
Abstract Fiber reinforced polymer (FRP) wrapping technology is commonly used to enhance the compressive strength (CS) of reinforced concrete (RC) members. Accurate prediction of the compressive strength of FRP‐confined concrete columns is crucial for optimizing structural design and helps reduce the time and costs associated with physical testing ...

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,
