    • Analysis of the Influence of Crystalline Admixtures at Early Age Performance of Cement-Based Mortar by Electrical Resistance Monitoring 

      Beltrán Cobos, Rubén; Tavares, Fabiano; Sánchez Moreno, Mercedes (MDPI, 2021)
      Crystalline admixtures are employed for waterproofing concrete. This type of admixtures can affect the early age performance of cement-based mixes. The electrical resistance properties of cement have been related to the ...

    • Anodic growth of passive layers on steel rebars in an alkaline medium simulating the concrete pores 

      Sánchez Moreno, Mercedes; Gregori, J.; Alonso, M.C.; García Jareño, J.J.; Vicente, F. (Elsevier, 2006)
      Electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV) techniques have been used to study passive layers anodically grown on steel rebars in an aqueous alkaline solution simulating the electrolyte of the ...

    • Calcium aluminate based cement for concrete to be used as thermal energy storage in solar thermal electricity plants 

      Alonso, María Cruz; Vera-Agullo, José; Flor-Laguna, Virtudes; Guerreiro, Luis; Sánchez Moreno, Mercedes; Collares-Pereira, Maria (Elsevier, 2016)
      A concept for thermal energy storage (TES) in concrete as solid media for sensible heat storage is proposed to improve the cost and efficiency of solar thermal electricity (STE) plants. Mortar and concrete mixes were ...

    • Colloidal Nanosilica Treatments for Sealing Cracks in Mortar 

      Sánchez Moreno, Mercedes; García Calvo, José Luis; Tavares, Fabiano (MDPI, 2022)
      Presence of microcracks in concrete can diminish the service life of a structure. The injection of materials for filling the crack is proposed for facing this problem. The traditional materials used for sealing cracks ...

    • Electrochemical and analytical assessment of galvanized steel reinforcement pre-treated with Ce and La salts under alkaline media 

      Sánchez Moreno, Mercedes; Alonso, M.C.; Cecílio, P.; Montemor, M.F.; Andrade, C. (Elsevier, 2006)
      The present work aims at evaluating the ability of cerium and lanthanum conversion pre-treatments applied on galvanized rebars to hinder the cathodic process of hydrogen release during the early stages of contact between ...

    • Experimental Characterization of the Self-Healing Capacity of Cement Based Materials: An Overview 

      Ferrara, Liberato; Cuenca Asensio, Estefania; Lo Monte, Francesco; Roig Flores, Marta; Sánchez Moreno, Mercedes; Snoeck, Didier; Van Mullem, Tim; Belie, Nele De (MDPI, 2018)
      This paper, prepared in the framework of the COST Action SARCOS WG2 activities (http://www.cost.eu/COST_Actions/ca/CA15202), provides an overview of the main concepts underlying the experimental characterization of the ...

    • Improvement of the Concrete Permeability by Using Hydrophilic Blended Additive 

      García Calvo, José Luis; Sánchez Moreno, Mercedes; Carballosa, Pedro; Pedrosa, Filipe; Tavares, Fabiano (MDPI, 2019)
      Crystalline hydrophilic additives are increasingly used as efficient methods for reducing water permeability in concrete. Their effectiveness in hindering water penetration has been proven in different cementitious materials, ...

    • Preliminary attempt of hardened mortar sealing by colloidal nanosilica migration 

      Sánchez Moreno, Mercedes; Alonso, M.C.; Gónzález, R. (Elsevier, 2014)
      An innovative electrochemical treatment for the sealing of hardened mortar by nanosilica migration is proposed. The composition of the colloidal suspension and the electric field power were assessed as significant parameters ...

    • Ternary mixes with high mineral additions contents and corrosion related properties 

      Alonso, M.C.; García Calvo, José Luis; Sánchez Moreno, Mercedes; Fernández, A. (Wiley, 2013)
      The choice of blended cements and materials with cementitious properties inconcrete is currently seen as a choice that increases the environmentalsustainability of the construction industry. The developments with non-traditional ...

    • The Inhibitive Effect of Sebacate-Modified LDH on Concrete Steel Reinforcement Corrosion 

      Caballero, David; Beltrán Cobos, Rubén; Tavares, Fabiano; Cruz-Yusta, M.; Sánchez Granados, Luis; Sánchez Moreno, Mercedes; Pavlovic, I. (MDPI, 2022)
      In recent decades, layered double hydroxides (LDH) have been proposed as innovative corrosion inhibitors for reinforced concrete. Their protective action is based on the ability to intercalate specific anions in the ...
