Chloride penetration assessment on self-healing capability of conventional, high-performance, and ultra high-performance concrete

Doostkami, Hesam (Universitat Politècnica de València, 2024-09-02)

[ES] El hormigón, material de construcción fundamental en la ingeniería civil, ha sido muy estudiado para cuantificar y mejorar su resiliencia y vida útil. La exposi-ción prolongada a ciertas condiciones ambientales, y la ...
Effect of crystalline admixtures on the self-healing capability of early-age concrete studied by means of permeability and crack closing tests

Roig Flores, Marta; Pirritano, F.; Serna Ros, Pedro; Ferrara, L. (Elsevier, 2016-07)

This paper analyzes the self-healing properties of early-age concretes, engineered using a crystalline admixture (4% by the weight of cement), by measuring the permeability of cracked specimens and their crack width. Two ...
Effects of autogenous healing on the recovery of mechanical performance of High Performance Fibre Reinforced Cementitious Composites (HPFRCCs): Part 1

Ferrara, Liberato; Krelani, V.; Moretti, F.; Roig-Flores, M.; Serna Ros, Pedro (Elsevier, 2017)

[EN] This paper presents the results are shown of a thorough characterization of the self-healing capacity of High Performance Fibre Reinforced Cementitious Composites (HPFRCCs). The capacity of the material will be ...
Effects of healing start time and duration on Conventional and High-Performance Concretes incorporating SAP, crystalline admixture, and sepiolite: a comparative study

Doostkami, Hesam; Formagini, Sidiclei; Serna, Pedro; Roig-Flores, Marta (Elsevier, 2024-07)

[EN] This research investigates the self-healing capability of conventional and high-performance concrete containing either a superabsorbent polymer (SAP), a crystalline admixture (CA), or water-encapsulated in sepiolite ...
Evaluation of the Self-healing Capability of Ultra-High-Performance Fiber-Reinforced Concrete with Nano-Particles and Crystalline Admixtures by Means of Permeability

Doostkami, Hesam; Roig-Flores, Marta; Negrini, Alberto; Mezquida-Alcaraz, Eduardo J.; Serna Ros, Pedro (Springer, 2020-09-22)

[EN] Self-healing is the capability of a material to repair its damage autonomously. Ultra-High-Performance Fiber Reinforced Concrete (UHPFRC) has potentially higher self-healing properties than conventional concrete because ...
