Deformation Recovery of Reinforced Concrete Beams Made With Recycled Coarse Aggregates
(Elsevier, 2022)[Abstract] The purpose of this research is to analyse the long-term deformations of reinforced concrete beams made of recycled coarse aggregates (RCA), using four different replacement ratios, 0%, 20%, 50% and 100%. For ... -
Design and properties of cement coating with mussel shell fine aggregate
(Elsevier, 2019)[Abstract:] The production of farmed mussels amounts to millions of tonnes across over 40 countries. Shell waste resulting from this production has a very significant environmental impact. In Galicia, mussel shell waste ... -
Determining the U-Value of Façades Using the Thermometric Method: potentials and limitations
(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. ... -
Effect of 10% recycled sands from various storage sites on the mortar’s properties
(Taylor & Francis, 2023)[Abstract:] This study investigates the effects of using 10% of recycled sand in mortars. Using the concrete equivalent mortar approach, the reference mortar was developed from a flowable natural aggregate concrete with a ... -
Effect of fine and coarse recycled concrete aggregate on the mechanical behavior of precast reinforced beams: Comparison of FE simulations, theoretical, and experimental results on real scale beams
(Elsevier, 2018)[Abstract:] In this work, we present the effect of using coarse and fine recycled aggregate jointly as a partial replacement of natural aggregate in self-compacting concrete in the mechanical performance of precast beams. ... -
Effect of KyAl4(Si8-y) O20(OH)4 Calcined Based-Clay on the Microstructure and Mechanical Performances of High-Performance Concrete
(MDPI, 2021)[Abstract:] The work described in this paper has been performed to determine the potential use of meta-illite (KyAl4(Si8-y) O20(OH)4) calcined clay (MCC) as a supplementary cementitious material (SCM) in a binary Portland ... -
Effects of bacteria-based self-healing nutrients on hydration and rheology of cement pastes
(Elsevier, 2023)[Abstract:] Crack openings in concrete lead to a reduction in its lifespan. Many authors have analysed different techniques that could repair cracks autonomously, being the use of bacteria one of the most promising approaches. ... -
Effects of mussel shell aggregates on hygric behaviour of air lime mortar at different ages
(Elsevier, 2020)[Abstract:] Mussel shells, composed of calcium carbonate (>95%) and organic matter, are suitable alternatives to conventional sand in mortar. In addition, the use of lime instead of cement as a binder has also been considered ... -
Estimating Adaptive Setpoint Temperatures Using Weather Stations
(MDPI, 2019)[Abstract] Reducing both the energy consumption and CO2 emissions of buildings is nowadays one of the main objectives of society. The use of heating and cooling equipment is among the main causes of energy consumption. ... -
Estudio comparativo de los métodos para evaluar la transmitancia térmica en cerramientos opacos en el invierno mediterráneo
(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 ... -
Evaluation of self-compacting recycled concrete robustness by statistical approach
(Elsevier, 2018)[Abstract:] The use of self-compacting recycled concrete appears as to be a very interesting technology for the sustainable construction future. However, one of the major obstacles to a more widespread use of self-compacting ... -
Flexural performance of reinforced concrete beams made with recycled concrete coarse aggregate
(Elsevier, 2018)[Abstract:] This work deals with the flexural performance of recycled concrete subjected to increasing loads up to failure. For this purpose, eight reinforced concrete beams were made with recycled coarse aggregates using ... -
Genetic programming to understand the influence of new sustainable powder materials in the fresh performance of cement pastes
(Elsevier, 2024)[Abstract:] This study focused on pastes that incorporate metakaolin, biomass ash, and granite powder as supplementary cementitious materials to obtain specific expressions to predict rheological properties in pastes and ... -
Impact of mussel shell aggregates on air lime mortars. Pore structure and carbonation
(Elsevier, 2019)[Abstract:] Galician “Rías”·conditions (extension, water temperature …. ) enable the production of excellent quality cultured mussels. This leads Spain to be the third producer country in the world. Cannery industry (35% ... -
Industrial low-clinker precast elements using recycled aggregates
(MDPI, 2020)[Abstract:] Increasing amounts of sustainable concretes are being used as society becomes more aware of the environment. This paper attempts to evaluate the properties of precast concrete elements formed with recycled ... -
Influence of the Mixing Procedure on the Fresh State Behaviour of Recycled Mortars
(Elsevier, 2021)[Abstract] The effect of two different mixing protocols on the fresh-state behaviour of self-compacting mortars with and without recycled sand was compared. For this purpose, the mortar mixes were designed considering three ... -
Internally cured high performance concrete with magnesium based expansive agent using coal bottom ash particles as water reservoirs
(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 ... -
Long-term flexural performance of reinforced concrete beams with recycled coarse aggregates
(Elsevier, 2018)[Abstract:] The aim of this study is to investigate the behaviour of recycled aggregate concrete subjected to sustained loading. For the tests, eight reinforced concrete beams were manufactured with recycled coarse aggregate, ... -
