Electrical resistivity-based approach to characterize moisture content in compressed earth bricks
Autor: Tuan Anh Nguyen, Minh Dung Pham, Wael Hafsa, Nicolas Angellier, Laurent Ulmet, Frédéric Dubois
Publikováno v: Case Studies in Construction Materials, Vol 21, Iss , Pp e04027- (2024)
Compressed earth bricks (CEBs) are increasingly used as a sustainable building material, but their hygroscopic nature makes them susceptible to moisture-related degradation. Monitoring moisture content in CEBs is crucial for ensuring structural integ
