Analysis of Tensile Behavior of Recycled Aggregate Concrete Using Acoustic Emission Technique
(RILEM Publications SARL, 2020)[Abstract] Recycled concrete aggregate (RCA) was processed from reinforced concrete edge beams sourced from a demolished bridge. This material replaced different ratios of coarse aggregate in a benchmark concrete. The ... -
Assessment of the Durability Dynamics of High-Performance Concrete Blended With a Fibrous Rice Husk Ash
(MDPI, 2022)[Abstract] The present study examines the durability properties of Class 1 (50–75 MPa) high-performance concrete (HPC) blended with rice husk ash (RHA) as a partial replacement of CEM II B-L, 42.5 N. Six HPC mixes were ... -
Assessment of Water Transport and Chemical Attack of Meta-Illite Calcined Clay Blended Cement in High-Performance Concrete
(MDPI, 2023)[Abstract:] Rapid urbanisation causes a rise in the need for infrastructure, which in turn fuels the creation of additional concrete and further increases cement supplies. Activation of illite-based clay mineral and usage ... -
Automated Control of the Fresh State of Industrial Concrete Behaviour by Rheometer Test Adjustment
(MDPI, 2023)[Abstract:] This study aimed to develop a rheometer prototype and define a procedure for adjusting the automated control of the fresh state of concrete. Sixteen batches were produced, and their fresh behaviour was measured ... -
Caracterización experimental de anclajes post instalados de gran capacidad en situaciones sísmicas
(Asociación Española de Ingeniería Estructural (ACHE), 2022)[Resumen:] A medida que mejoran la tecnología y disponibilidad de las resinas, el campo de aplicación del anclaje post instalado se va extendiendo a situaciones de mayor demanda mecánica. En el caso planteado en este ... -
Concrete with fine and coarse recycled aggregates: E-modulus evolution, compressive strength and non-destructive testing at early ages
(Elsevier, 2018)[Abstract:] The combined use of fine and coarse recycled aggregates in the manufacture of concrete has multiple advantages from the economic and environmental points of view. There is a lack of knowledge about the behavior ... -
Cunchas de mexillón para o desenvolvemento do material de construción
(ADEGA (Asociación para a Defensa Ecolóxica de Galiza), 2021)[Resumo:] Proxecto Biovalvo, desenvolvido polo Grupo de Construción da Universidade da Coruña (UDC) e coa participación de diversas empresas, incluíu entre os seus obxectivos a aplicación das cunchas de mexillón como ... -
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 ... -
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 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. ... -
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 ... -
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 ... -
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 ... -
