An Embedded-Sensor Approach for Concrete Resistivity Measurement in On-Site Corrosion Monitoring: Cell Constants Determination

Ramón, Jose Enrique; Martínez, Isabel; Gandía-Romero, Jose M.; Soto Camino, Juan (MDPI AG, 2021-04)

[EN] The concrete electrical resistivity is a prominent parameter in structural health monitoring, since, along with corrosion potential, it provides relevant qualitative diagnosis of the reinforcement corrosion. This study ...
Application of microwaves dielectric spectroscopy for controlling osmotic dehydration of kiwifruit (Actinidia deliciosa cv Hayward)

Castro Giráldez, Marta; Fito Suñer, Pedro José; Dalla Rosa, Marco; Fito Maupoey, Pedro (Elsevier, 2011-10)

[EN] Dielectric spectroscopy studies have been performed on fresh and osmotically dehydrated kiwifruits (Actinidia deliciosa cv Hayward). The osmotic treatment consisted on the immersion the samples into 65% (w/w) sucrose ...
Improved Tafel-Based Potentiostatic Approach for Corrosion Rate Monitoring of Reinforcing Steel

Ramón, José Enrique; Martínez, Isabel; Gandía-Romero, Jose M.; Soto Camino, Juan (Springer-Verlag, 2022-12)

[EN] Potential step voltammetry (PSV) was introduced in earlier works as an advantageous alternative to traditional methods for measuring corrosion rate in reinforced concrete. The present study aims to improve PSV to ...
Potential step voltammetry: An approach to corrosion rate measurement of reinforcements in concrete

Ramón, J.E.; Gandía-Romero, Jose M.; Bataller Prats, Román; Alcañiz Fillol, Miguel; Valcuende Payá, Manuel Octavio; Soto Camino, Juan (Elsevier, 2020-07)

[EN] This paper presents a Potentiostatic Step Voltammetry approach to corrosion rate measurement of reinforcements in concrete. We have termed this approach PSV-TE since it is based on the Tafel extrapolation method, but ...
Power Spectral Density method performance in detecting damages by chloride attack on coastal RC bridge

Hadizadeh-Bazaz, Mehrdad; Navarro, Ignacio J.; Yepes, V. (Techno-Press, 2023-01-25)

[EN] The deterioration caused by chloride penetration and carbonation plays a significant role in a concrete structure in a marine environment. The chloride corrosion in some marine concrete structures is invisible but can ...
Real-time corrosion monitoring of an ultra-high performance fibre-reinforced concrete offshore raft by using an autonomous sensor sytem

Ramón Zamora, José Enrique; Gandía-Romero, Jose M.; Bataller Prats, Román; López, Juan A.; Valcuende Payá, Manuel Octavio; Soto Camino, Juan (John Wiley & Sons, 2022-11)

[EN] 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, ...
Ultrasonic monitoring of lard crystallization during storage

Santacatalina Bonet, Juan Vicente; García Pérez, José Vicente; Corona Jiménez, Edith; Benedito Fort, José Javier (Elsevier, 2011-01)

[EN] This work addresses the use of ultrasonics as a non-destructive technique with which to monitor lard crystallization during cooling and storage. The ultrasonic velocity was measured during both the isothermal ...
Utilización de la técnica de ultrasonidos para la detección, bajo simulación en laboratorio, de galerías producidas por el picudo rojo en palmeras Phoenix sp

Jorge García, David (Universitat Politècnica de València, 2015-09-02)

[EN] In recent years, the emergence of Rhynchophorus ferrugineus (red palm weevil) is affecting the palms of the Mediterranean area and particularly in the Levantine one. Its effects are visible in gardens as well as in ...
Waterfront Depth Analysis in Hardened Concrete by Means of the Nondestructive Ground-Penetrating Radar Technique

Rodríguez-Abad, Isabel; Klysz, Gilles; Martínez-Sala, Rosa M.; Balayssac, Jean Paul; Mene-Aparicio, Jesus (Institute of Electrical and Electronics Engineers (IEEE), 2016-01-29)

Durability of concrete structures depends mainly on the ease whereby water and any aggressive chemical agents dissolved therein can penetrate. Therefore, measuring water penetrability in concrete structures is crucial ...
