Autogenous self‐healing of concrete: Experimental design and test methodsA review
Engineering Reports, Volume 5, Issue 1, January 2023., 2023 Concrete exhibits an intrinsic ability to heal cracks, defined as “autogenous self‐healing.” However, despite code restrictions, autogenous self‐healing of concrete shows limited effectiveness in practice. This indicates the need for further research to provide engineers with reliable design rules.

Application of Hilbert instantaneous spectrum on improved bolt anchoring quality detection
Engineering Reports, Volume 4, Issue 12, December 2022., 2022 A method utilizing a way to compute the instantaneous frequency curve of the bolt signal is proposed to overcome the phase folding problem existing in the Hilbert transform spectrum. The instantaneous frequency curve of the signal can help accurately identify the reflected signal from the bolt bottom and the position of the defect, thus accurately ...

Earthquake Engineering &Structural Dynamics, Volume 52, Issue 2, Page 308-334, February 2023., 2023 Abstract Unreinforced masonry (URM) buildings are highly vulnerable to seismic ground motion, calling for quantitative risk assessment and mitigation programmes in different earthquake‐prone countries to reduce future losses. Despite the effectiveness of base isolation technology in reducing seismic response of buildings, the high costs of conventional

Earth Surface Processes and Landforms, Volume 47, Issue 15, Page 3453-3464, December 2022., 2022 We evaluate the biogeomorphological impacts of seaweed on materials commonly used in maritime built heritage restoration. After 6 months of exposure to intertidal conditions, we found no evidence of enhanced deterioration of mortar prepared using natural cement when covered with seaweed compared to uncovered mortar.

Materials and Corrosion, EarlyView., 2021 Several methods to measure the critical chloride content Ccrit of steel in concrete are compared on the basis of 12% chromium steel and carbon steel. The resulting Ccrit depends on the method used. The reasons for this and the corresponding influencing parameters are discussed in this article.

An Integrated Experimental-Numerical Study of the Performance of Lime-Based Mortars in Masonry Piers Under Eccentric Loading [PDF]
Construction and Building Materials 114, 913--926, (2016), 2015 Architectural conservation and repair are becoming increasingly important issues in many countries due to numerous prior improper interventions, including the use of inappropriate repair materials over time. As a result, the composition of repair masonry mortars is now being more frequently addressed in mortar research.

Recycled nylon fibers as cement mortar reinforcement [PDF]
Construction and Building Materials, 80, 200-209, 2015. ISSN:
0950-0618, 2014 We investigate engineering applications of recycled nylon fibers obtained from waste fishing nets, focusing our attention on the use of recycled nylon fibers as tensile reinforcement of cementitious mortars. We begin by characterizing the tensile behavior of both unconditioned and alkali-cured recycled nylon fibers obtained through manual cutting of ...
