A review of fracture propagation in concrete: fundamentals, experimental techniques, modelling and applications
(ICE Publishing, 2023) Barbhuiya, S.; Das, B.B.; Kanavaris, F.
A comprehensive overview of fracture propagation in concrete, covering various aspects ranging from fundamentals to applications and future directions, is presented. The introduction presents an overview of fracture propagation in concrete, emphasising its importance in understanding the behaviour of concrete structures. The fundamentals of fracture propagation are then explored, including concrete as a composite material, crack initiation and propagation mechanisms, types of fractures and the factors that influence fracture propagation. Next, experimental techniques for studying fracture propagation are discussed, encompassing both destructive and non-destructive testing methods, such as acoustic emission, ultrasonic testing, digital image correlation and advanced imaging techniques like X-ray computed tomography and scanning electron microscopy. Modelling approaches, including continuum damage mechanics, the finite-element method, the discrete-element method, the lattice discrete particle model and hybrid models, for simulating and predicting fracture propagation behaviour are then reviewed. The applications of fracture propagation in concrete are highlighted, including structural health monitoring, design optimisation, failure analysis and repair and rehabilitation strategies. Research opportunities for further improvement are addressed. This article should serve as a valuable resource for researchers, engineers and professionals in the field, providing a comprehensive understanding of fracture propagation in concrete and guiding future research endeavours. © 2023 Emerald Publishing Limited: All rights reserved.

Ground waste glass as a supplementary cementitious material for concrete: sustainable utilization, material performance and environmental considerations
(Taylor and Francis Ltd., 2025) Barbhuiya, S.; Kanavaris, F.; Ashish, D.K.; Tu, W.; Das, B.B.; Adak, D.
This review article delves into the role, potential, and peculiarities of ground waste glass (GWG) as both a supplementary cementitious material (SCM) and a filler in concrete. Motivated by the increasing emphasis on sustainable construction practices, the article explores the potential of GWG in enhancing concrete performance while addressing environmental concerns associated with traditional materials. The comprehensive review encompasses the properties of GWG as an SCM, its global availability, its influence on various concrete properties, its compatibility with cementitious systems, optimization techniques, challenges, and practical applications. Key considerations such as particle size distribution, replacement levels, and chemical activation in optimizing recycled GWG incorporation are also highlighted. This comprehensive review underscores the potential of GWG as a sustainable additive in concrete, enhancing both environmental responsibility and structural performance. © 2025 The Author(s).
