Adhesion Analysis of Waste Cork Dust as Filler for Bituminous Mixtures
Pasandín, A.R.; Galán-Díaz, Juan José; Pérez Pérez, Ignacio (Taylor & Francis, 2020)[Abstract] Suberin is a biopolymer that can be found in high amounts in natural cork. As is well known, polymers can be used as bitumen modifiers to improve the properties of bituminous mixtures. This paper describes ... -
Comparison of accelerated laboratory curing and maturation under uncontrolled conditions of gravel emulsions using a nonlinear weighted least-squares predictive model
Pasandín, A.R.; Galán-Díaz, Juan José; Silva, Luís M. S.; Orosa, Pablo; Pérez Pérez, Ignacio (Taylor & Francis, 2022)[Abstract:] Cold-asphalt mixtures (CAMs) are evolved materials whose mechanical strength increases with their maturation. The relationship between CAM field maturation and laboratory-accelerated cure procedures is not well ... -
Evaluation of the Resilient Modulus of Hot-Mix Asphalt Made With Recycled Concrete Aggregates From Construction and Demolition Waste
Galán-Díaz, Juan José; Silva, Luís M. S.; Pasandín, A.R.; Pérez Pérez, Ignacio (MDPI, 2020)[Abstract] This paper reports the influence of the percentage of recycled aggregate (RCA) from construction and demolition waste (C&DW) together with the percentage of binder (L), curing time (t) and temperature (T) of the ... -
Fatigue Study of the Pre-Corroded 6082-T6 Aluminum Alloy in Saline Atmosphere
Fernández Muñoz, Alejandro; Mier, Jose; García-Diez, Ana; Camba, C.; Galán-Díaz, Juan José (MDPI, 2020-09)[Abstract] This work studies the influence of the saline atmospheric corrosion on the fatigue strength of 6061-T6 aluminum alloy. For this purpose, this alloy was subjected to tests in a salt spray corrosion chamber at ... -
Importancia de los preconceptos en la adquisición de conocimientos en materias científico-técnicas
Galán-Díaz, Juan José; Toledano, Mar; Fernández Garrido, Simón; García Fernández, María del Carmen; Martínez-Díaz, Margarita (Universidade da Coruña, Servizo de Publicacións, 2021)[Resumen] La cantidad de preconceptos que los alumnos poseen antes de abordar el estudio de un tema influye de manera notable en la adquisición de nuevos conocimientos. Se ha diseñado una estrategia de enseñanza aprendizaje ... -
Mechanical behavior of hot-mix asphalt made with recycled concrete aggregates from construction and demolition waste: a design of experiments approach
Galán-Díaz, Juan José; Silva, Luís M. S.; Pérez Pérez, Ignacio; Pasandín, A.R. (MDPI, 2019)[Abstract:] The present work is a re-evaluation of previous research on the durability of hot-mix asphalt made with recycled concrete aggregates from construction and demolition waste (CDW) with a different approach. ... -
O traballo das mulleres en ámbitos marítimos: mariña mercante e pesca
Campa Portela, Rosa Mary de la; Martínez-Díaz, Margarita; Galán-Díaz, Juan José; Fernández Garrido, Simón (Universidade da Coruña, 2013)[Resumo] Aínda que a igualdade de xénero se establece como unha prioridade no marco lexislativo de todos os países que conforman a Unión Europea, a prevalencia dos estereotipos sociais que asignan un determinado rol a homes ... -
Physical and hydraulic properties of porous concrete
Sánchez-Mendieta, Carlos; Galán-Díaz, Juan José; Martínez-Lage, Isabel (MDPI, 2021)[Abstract:] The work presented includes a review of the state of art of porous concrete. Its purpose is to evaluate the potential use of porous concrete in constructions where the level of surface runoff justifies it. A ... -
Preliminary investigation on the use of waste cork dust as filler in hot-mix asphalt
Pasandín, A.R.; Galán-Díaz, Juan José; Pérez Pérez, Ignacio (2019)[Abstract:] The cork contains significant amounts of a biopolymer called suberin (45%). Polymers have been frequently used in the manufacture of hot-mix asphalt (HMA) to improve their properties. At the Universidade da ... -
