Application of electrochemical methods for studying steel corrosion in alkali‐activated materials

Materials and Corrosion, Volume 74, Issue 7, Page 988-1008, July 2023., 2023
Studies on the corrosion of steel reinforcement in alkali‐activated materials (AAMs) are reviewed. It is demonstrated that important differences exist between steel corrosion in AAMs and conventional cement, and between different classes of AAMs, which affect the outcomes and the interpretation of electrochemical measurements. Abstract Alkali‐activated

Real‐time corrosion monitoring of an ultra‐high performance fibre‐reinforced concrete offshore raft by using an autonomous sensor system

Structural Control and Health Monitoring, Volume 29, Issue 11, November 2022., 2022
Summary The excellent high‐durability features of ultra‐high performance fibre‐reinforced concrete (UHPFRC) have been verified in laboratory studies, but its performance under service conditions are being studied. Indeed, structural health monitoring (SHM) can be considered an efficient strategy to assess built structures in which concrete matrix ...

Kinetic study of the transformation of sodalite to nepheline

Journal of the American Ceramic Society, Volume 105, Issue 6, Page 4336-4347, June 2022., 2022
Abstract The kinetics and mechanism of the development of nepheline (NaAlSiO4) through thermal transformation of sodalite (Na4Al3Si3O12Cl) was studied by means of differential thermal analysis at different heating rates (10°C min−1 to 50°C min−1) to control the evolution of the crystallization fraction.

Numerical and Experimental Analysis of Self‐Protection in Reinforced Concrete due to Application of Mg–Al–NO2 Layered Double Hydroxides

Advanced Engineering Materials, Volume 22, Issue 11, November 2020., 2020
Mg–Al–NO2 layered double hydroxide (LDH) is incorporated in concrete to increase the amount of bound chlorides. The performance of LDH is evaluated by modeling the chloride transport in concrete using finite element analysis. In situ X‐ray diffraction (XRD) and calorimetry analysis help in understanding the reactiveness and stability of LDH particles ...
