Raman Spectroscopic Analysis and In Situ Heating Experiments on Adranosite Minerals

open access: yesJournal of Raman Spectroscopy, EarlyView.
This study provides the first detailed Raman spectroscopic characterization of rare ammonium sulfates adranosite, iron‐rich adranosite, and adranosite‐(Fe) from volcanic and coal‐fire environments. Distinct spectral features reveal compositional differences and structural effects of Fe substitution.

Benchmarking Potential Construction Waste Streams and Their Climate Impact: Life Cycle Assessment‐Based Targets for Strategic Planning of Construction Processes

open access: yesSustainable Development, EarlyView.
ABSTRACT This study investigates how construction waste intensity affects greenhouse gas emissions (GHGe), analyzing data from 345 buildings constructed between 2007 and 2025. Using material waste rates (MWR) from previous cases, it predicts climate impacts based on typical material compositions.

A Scoping Review of Construction and Demolition Waste Management and the Sustainable Development Goals: Evidence From Brazil

open access: yesSustainable Development, EarlyView.
ABSTRACT Construction and demolition waste (CDW) management poses significant challenges but also offers opportunities for advancing sustainable development, especially in rapidly urbanizing countries such as Brazil. This scoping review examines the relationship between CDW management practices in Brazil and the United Nations Sustainable Development ...

Assessment of Soiling Dynamics and Cleaning Efficiency for Photovoltaic Modules Under Different Dust Environments

open access: yesSolar RRL, EarlyView.
A laboratory framework reproduces site‐specific soiling and cleaning dynamics of photovoltaic modules using real dusts from contrasting climates. Accelerated humidity–temperature cycling replicates 1 month of outdoor cementation in only ≈ 1.5 days.

Enhancing printability of 3D printed concrete by using metakaolin and silica fume

open access: yesStructural Concrete, EarlyView.
Abstract This study investigates the effects of incorporating metakaolin (MK) and silica fume (SF) on the fresh and hardened properties of 3D printed concrete (3DPC). Five mix designs were prepared with MK replacement levels of 0%, 10%, 12.5%, and 15%, along with one mix containing 10% MK and 5% SF.

Toward transparent AI: Predicting strength of fly ash foam composite concrete using explainable ML models

open access: yesStructural Concrete, EarlyView.
Abstract Fly ash foam composite concrete (FFC) is a sustainable, lightweight alternative to traditional concrete. However, accurately predicting its compressive strength (CS) through conventional laboratory methods is challenging due to its non‐linear behavior induced by the addition of foam content and fly ash. Also, the laboratory determination of CS
