The mechanical resistance of saturated stones [PDF]

open access: yes, 2010
This paper aims at investigating the effect of the presence of water on the mechanical resistance of stones. The presence of water, connected to the intrinsic properties of the stone (mineralogical composition, fabric, texture, etc.) and to the ...

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

open access: yesEngineering 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.

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

open access: yesRevista 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.

Hybrid NDT‐Machine Learning Framework With SHAP‐Based Interpretation for Predicting Compressive Strength of Steel Slag Concrete

open access: yesEngineering 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

open access: yesJournal 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)

Dimensional stability and water transport behavior of concrete with high contents of wind‐turbine blade waste

open access: yesStructural Concrete, Volume 27, Issue 1, Page 758-776, February 2026.
Abstract Fiber addition is a common strategy to enhance concrete's durability, avoiding cracks and reducing penetration of harmful agents. In this research, a sustainable fiber‐like material obtained from mechanical recycling of dismantled wind‐turbine blades and made up of glass fiber‐reinforced polymer (GFRP) fibers and microfibers, balsa wood, and ...

Elastic Properties of Concrete Incorporating Ogugu Lateritic Sand as Fine Aggregate

open access: yesThe Journal of Engineering, Volume 2026, Issue 1, January/December 2026.
This study investigates the substitution of conventional fine aggregate with Ogugu lateritic sand in concrete grades 25 and 50, focusing on elastic behavior and strength development. The results show that laterized concrete achieves significant strength gains over time, with grade 25 compressive strength increasing from 14.11 N/mm2 at 3 days to 32.27 N/
