Aplicación de bacterias en hormigón y mortero como método de autosanado

Estacio Cumberbatch, Javier de Jesús (Universitat Politècnica de València, 2021-12-14)

[ES] La presencia de pequeñas fisuras en el hormigón armado suele ser inevitable. Esto se debe a su baja resistencia a tracción en comparación con su resistencia a compresión. Estas fisuras pueden dar paso a agentes agresivos ...
Concrete Early-Age Crack Closing by Autogenous Healing

Roig-Flores, Marta; Serna Ros, Pedro (MDPI AG, 2020-06)

[EN] Autogenous healing is mainly produced by continuing hydration or carbonation. The aim of this research is to quantify the crack closing produced by autogenous healing for early-age concrete. This healing was evaluated ...
Experimental investigation on the bond behaviour of steel reinforcement in self-healing concrete

Hermawan, Harry; Wiktor, Virginie; Gruyaert, Elke; Serna Ros, Pedro (Elsevier, 2023-06-20)

[EN] The appearance of cracks in structural reinforced concrete is inevitable and when out of control, it can be the cause of concrete failure. The ingress of water and harmful substances via the cracks is critical as the ...
Mix design optimisation of self-sealing concrete containing microcapsules with polyurethane shell and water repellent cargo

Hermawan, Harry; Riordan, Claire; van Der Sichel, Seppe; Lust, Louis; Serna Ros, Pedro; Palmer, Dave; Al-Tabbaa, Abir; Gruyaert, Elke (Elsevier, 2024-04)

[EN] Despite the robust ability of microcapsules (MIC) to break and release agent for healing/sealing efficacy, the reduction of concrete strength has been a major issue when using MIC. In this study, the optimisation of ...
Optimised Mix designs for Self-Healing Concrete

Hermawan, Harry (Universitat Politècnica de València, 2024-01-23)

[ES] El hormigón es considerado como uno de los principales materiales de construcción más ampliamente utilizado en obras de infraestructuras. Su consideración como material de gran durabilidad y su ventajosa relación ...
Prediction of Aggregate Packing with Tubular Macrocapsules in the Inert Structure of Self-Healing Concrete Based on Dewar's Particle Packing Model

Hermawan, Harry; Simons, Alicia; Teirlynck, Silke; Anglani, Giovanni; Serna Ros, Pedro; Tulliani, Jean-Marc; Antonaci, Paola; Minne, Peter; Gruyaert, Elke (MDPI AG, 2024-05)

[EN] This paper brings a new insight into understanding the influence of macrocapsules in packing systems, which can be useful in designing the inert structure of self-healing concrete. A variety of tubular macrocapsules, ...
