Liang, M. (author), Xie, J. (author), He, S. (author), Chen, Y. (author), Schlangen, E. (author), Šavija, B. (author)Early-age cracking risk induced by autogenous deformation is high for cementitious materials of low water-binder ratios. The autogenous deformation, viscoelastic properties, and stress evolution are three important factors for understanding and quantifying the early-age cracking risk. This paper systematically reviewed the experimental and...review 2024

Liang, M. (author), Schlangen, E. (author), Šavija, B. (author)Stress evolution of restrained concrete is directly related to early-age cracking (EAC) potential of concrete, which is a tricky problem that often happens in engineering practice.

Ibrahim, M.S. (author), Poliotti, M. (author), Yang, Y. (author), Hendriks, M.A.N. (author)Typically precast girders are designed and utilized as simple supported members. Alternatively, the precast girders can be made continuous at the intermediate support using cast-in-place concrete topping. Once the girders are made continuous, time-dependent restraint moments will occur. The magnitude of the restraint moment is mainly affected by...conference paper 2023

Poulis, J.A. (author), Seymour, Kate (author), Mosleh, Yasmine (author)Canvas paintings are prone to environmental ageing. Hence, the structural conservation of canvas paintings may require lining, a process in which a secondary canvas is adhered to the reverse of the damaged original canvas to provide additional support. Choosing the optimum adhesive in combination with a lining method is crucial and yet...journal article 2022

Hu, Z. (author), Wyrzykowski, M. (author), Lura, P. (author)Creep at early ages significantly affects the volumetric deformation of cementitious materials. Efficient modelling of early-age creep is a challenging task, mainly due to continuously evolving material properties (hydration) and other phenomena (e.g. autogenous shrinkage) taking place in parallel. Various methods were introduced during the past...conference paper 2021
