Multiple Scattering Suppression in Heterogeneous Media: High‐Precision Imaging of Sleeve Grouting Defects Based on Elastic Reverse Time Migration

Engineering Reports, Volume 8, Issue 6, June 2026.
This study proposes an elastic wave reverse time migration (RTM) method to suppress multiple scattering noise in heterogeneous concrete. By effectively utilizing scattered wavefields, RTM enables high‐precision, robust imaging of sleeve grouting defects in prefabricated buildings, significantly outperforming traditional algorithms.

A new approach to estimate compressive strength of concrete by the UPV method

Revista IBRACON de Estruturas e Materiais
Although the ultrasonic pulse velocity (UPV) method has been extensively used to estimate concrete compressive strength, the relationship between UPV and concrete strength is mixture dependent.

Domain Wall Rebounds Driven by Competing Entropic and Spin‐Transfer Torques in Cylindrical Nanowires

Advanced Functional Materials, Volume 36, Issue 41, 21 May 2026.
Domain‐wall motion in cylindrical magnetic nanowires driven by nanosecond current pulses. Low current densities efficiently displace domain walls, whereas higher currents cause rebound at the wire ends. The effect results from the interplay between spin‐transfer torque and thermally induced processes, highlighting the role of thermal gradients in ...

External Vibrations on Early‐Age Concrete: A Review

Engineering Reports, Volume 8, Issue 5, May 2026.
Scientific illustration of external vibration, their influencing properties and effects, possible outcomes and measures adapted. ABSTRACT Early‐age concrete exhibits limited mechanical strength, making it highly susceptible to external disturbances such as vibrations from construction activities, traffic, or nearby machinery which can disrupt internal ...

Microstructure and Performance Optimization of Barley Husk Ash–Blended Mortars: A Sustainable Approach to Cement Substitution

Engineering Reports, Volume 8, Issue 4, April 2026.
Barley husk ash (BHA), an agricultural byproduct rich in pozzolanic oxides, was optimized as a sustainable cement substitute. Statistical modeling and experimental validation confirmed 22.75% BHA as the optimal replacement, enhancing mechanical and durability performance while advancing eco‐efficient construction practices.

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.

Low‐Carbon Composite Cement Mortar Incorporating Local Raw Materials as SCMs: Performance and Life Cycle Analysis

Journal of the American Ceramic Society, Volume 109, Issue 4, April 2026.
Overview of the experimental plan. ABSTRACT Performance and life cycle analysis of composite cement mortars developed using local conventional (blast furnace slag and fly ash) and novel non‐conventional (stone wool, glass wool, calcined Finnish clay, volcanic pozzolan Iceland, and ladle slag) raw materials as supplementary cementitious materials (SCMs)
