Determining the U-Value of Façades Using the Thermometric Method: potentials and limitations
Bienvenido Huertas, José David; Rodríguez-Álvaro, Roberto; Moyano, Juan; Rico Delgado, Fernando; Marín García, David (MDPI, 2018)[Abstract:] The thermal transmittance of building envelopes determines to a large extent the energy demand of buildings. Thus, there is a keen interest in having methods which can precisely evaluate thermal transmittance. ... -
Estudio comparativo de los métodos para evaluar la transmitancia térmica en cerramientos opacos en el invierno mediterráneo
Bienvenido Huertas, José David; Rodríguez-Álvaro, Roberto; Moyano, Juan; Marín García, David; Rico Delgado, Fernando (Instituto de Ciencias de la Construcción Eduardo Torroja (IETcc-CSIC), 2019)[Resumen:] En España, la mayor parte del parque inmobiliario presenta un comportamiento energético deficiente. Para paliar dicha situación, se debe analizar, entre otros aspectos, su envolvente. De las diferentes propiedades ... -
Internal curing of high-performance concrete via waste-based porous materials
Rodríguez-Álvaro, Roberto (2023)[Abstract] This work presents the use of different waste based porous materials as internal curing water reservoirs in high performance concrete, which is strongly aligned with the objective of promoting circularity in the ... -
Internally cured high performance concrete with magnesium based expansive agent using coal bottom ash particles as water reservoirs
Rodríguez-Álvaro, Roberto; González-Fonteboa, Belén; Seara Paz, Sindy; Hossain, Khandaker (Elsevier, 2020)[Abstract:] Shrinkage is one of the main concerns related to high performance concrete (HPC) durability. Its high density paste, consequence of a low water to binder ratio, can be unprofitable if cracks appear due to ... -
Masonry Mortars, Precast Concrete and Masonry Units Using Coal Bottom Ash as a Partial Replacement for Conventional Aggregates
Rodríguez-Álvaro, Roberto; González-Fonteboa, Belén; Seara Paz, Sindy; Rey-Bouzón, E. (Elsevier, 2021)[Abstract] Granular coal combustion products are problematic waste materials whose use as aggregates in concrete has been extensively studied. However, its integration into other non-structural materials and elements has ... -
Morteros para revestimiento con árido procedente de concha de mejillón
Rodríguez-Álvaro, Roberto (2014)[Resumen] El sector de la construcción genera un considerable volumen de residuos y contaminación a nivel global. En los últimos años se ha tomado conciencia de la necesidad de cambio, surgiendo el término bioconstrucción, ... -
Study of Different Granular By-Products as Internal Curing Water Reservoirs in Concrete
Rodríguez-Álvaro, Roberto; Seara Paz, Sindy; González-Fonteboa, Belén; Etxeberria, Miren (Elsevier, 2022)[Abstract] The use of three different waste-based materials, i.e. ceramic recycled aggregate (CRA), mixed recycled aggregate (MRA), and coal bottom ash (CBA), as internal curing water reservoirs was investigated. Their ... -
Use of granular coal combustion products as aggregates in structural concrete: Effects on properties and recommendations regarding mix design
Rodríguez-Álvaro, Roberto; Seara Paz, Sindy; González-Fonteboa, Belén; Martínez-Abella, Fernando (Elsevier, 2021)[Abstract:] This review collates the results obtained in more than 100 scientific publications regarding the performance of concrete with granular coal combustion products (GCCP, commonly referred to as coal bottom ash in ... -
Waste-Based Porous Materials as Water Reservoirs for the Internal Curing of Concrete. A Review
Rodríguez-Álvaro, Roberto; Seara Paz, Sindy; González-Fonteboa, Belén; Ferrándiz-Mas, Verónica; Paine, Kevin (Elsevier, 2021)[Abstract] This review collates findings from more than 100 scientific publications regarding the performance of several waste-based porous materials (WASPORs) as water reservoirs for the internal curing of concrete. Results ... -
Wood Ash Versus Expanded Clay Aggregate as Internal Curing Water Reservoirs in High Performance Concrete
Rodríguez-Álvaro, Roberto; González-Fonteboa, Belén; Seara Paz, Sindy; Tenza-Abril, Antonio José (Springer, 2022)[Abstract] The performances of expanded clay aggregate and wood ash as internal curing water reservoirs were studied in the mortar phase of a hypothetical high performance concrete with a low water-to-binder ratio. The two ...
