[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 ...
[EN] This work describes an innovation carried out during the course 2021/22 in the computer
sessions of the subject “Theory of Structures”, taught in Mechanical Engineering (third year
subject) and Industrial Technologies ...
[EN] This work studies the possibility of incorporating different proportions of glass powder from the waste glass (rejected material called fine cullet) produced during the glass recycling process into the manufacturing ...

[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 ...
[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 ...
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 ...
[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 ...

[EN] Heuristically known at least since the first half of XIX century, the self-healing capacity of cement-based materials has been receiving keen attention from the civil engineering community worldwide in the last decade. ...
[EN] Reinforced concrete elements frequently suffer small cracks that are not relevant from the mechanical point of view, but they can be an entrance point for aggressive agents, such as oxygen, which could initiate the ...
[EN] This study investigates the influence of operating temperatures on the mechanical properties of Fibre Reinforced Concretes (FRCs) when exposed during short-term periods (3 days). The studied parameters include types ...

[EN] The aim of this experimental work was to study the porous structure of Ultra-High-Performance Fibre-Reinforced Concretes (UH) made with different fibre volume contents (0%, 1%, 2%) under several curing conditions ...
[EN] Three-dimensional printed concrete (3DPC) is a relatively recent technology that may be very important in changing the traditional construction industry. The principal advantages of its use are more rapid construction, ...
[EN] The recycling of construction and demolition waste material reduces disposal of material and also the consumption of resources, therefore promoting sustainability in construction. Ultra-high performance concrete (UHPC) ...
The aim of this study is analyzing the self-healing effect of a crystalline admixture in four types of environmental exposure comparing with a reference concrete. Healing was studied by means of permeability tests on cracked ...
