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.
