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.

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.

Topics in Cement and Concrete Research [PDF]
In recent decades, the construction sector has faced many changes. One of these changes is the shift in the role of national government from one-sided practices in which the government was solely responsible for strategic and long-term spatial planning ...

This study explores the tensile behavior of carbon nanotube (CNT)–reinforced calcium silicate hydrate using molecular dynamics simulations. Multi‐walled CNTs demonstrate superior performance over single‐walled CNTs, with notable improvements in elastic modulus and tensile strength when the CNT orientation aligns with the loading direction.

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)
