Alkali-activated slag concrete: Fresh and hardened behaviour
(Elsevier, 2018)[Abstract:] The behaviour of fresh and hardened alkali-activated slag (AAS) and OPC concretes was compared and the effect of mixing time assessed. OPC and AAS concrete slump and rheological results proved to differ, ... -
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 mussel shells building solutions: A real-scale application
(Elsevier, 2021)[Abstract:] The construction sector is a key generator of greenhouse emissions, so the use of alternative low-emission building materials is a growing tendency. This work describes and analyses an innovative sustainable ... -
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 the permeability to aggressive agents of concrete with recycled cement and mixed recycled aggregate
(MDPI, 2021)[Abstract:] Acceptance by the construction industry of recycled concrete as a sustainable alternative material is contingent upon a reliable assessment of its permeability to corrosive agents. This study analyses the ... -
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 ... -
Automation and optimization of in-situ assessment of wall thermal transmittance using a Random Forest algorithm
(Elsevier, 2019-10-27)[Abstract]: Reducing energy consumption and greenhouse gases emissions is among the main challen-ges of building sector. It is therefore crucial to know the characteristics of envelopes. There are experimental methods to ... -
Bivalve Shells as a Building Material. A Real Case Application
(Springer Nature, 2023-07-22)[Abstract]: In a research project, Biovalvo Project, developed in the University of A Coruña, mussel shells by-products of the local canning industry were converted into a building material. The main milestone of the project ... -
Cajas de trabajabilidad como herramienta de diseño de hormigones autocompactantes con árido reciclado
(Universitat Politècnica de València UPV, 2018)[Resumen:] En este trabajo se diseñan siete hormigones autocompactantes convencionales y de cada uno de ellos se obtienen tres hormigones autocompactantes con árido grueso reciclado de hormigón (utilizando sustituciones ... -
Can mussel shell waste optimize cement and air lime mortars hygrothermal performance?
(Elsevier, 2024-10-23)[Abstract]: Mussel shells used as aggregates for mortars have flaky and irregular particles, which significantly increases the pore volume. This leads to the identification the microstructure of mussel shell mortars as a ... -
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 ... -
Carbonation evolution of lime putty coatings with mussel shell aggregate
(Elsevier, 2020)[Abstract:] The carbonation process is studied from young ages up to 2 years in mortars with fine mussel shell aggregate. Mussel shell aggregate affects lime mortars due to its shape (angular and flaky) and texture (smooth), ... -
Certificación energética en BIM
(Editorial Universitat Politècnica de València, 2019)[Abstract]: The BIM methodology stands out for trying to group the different stages of design, management, maintenance and even demolition and reincorporation into the environment of a building. These stages, also known ... -
Characterization of concrete behavior under cyclic loading using 2D digital image correlation
(Elsevier, 2023)[Abstract:] The development of plastic deformations of concrete during loading-unloading cycles and post-cracking behavior must be carefully controlled for accurate modeling of concrete structures. This study aims to ... -
Characterization of mussel shells as a bio-based building insulation material
(Association universitaire de génie civil, 2019-06-26)[Abstract]: In Galicia, 35% of mussel culture is intended for canning. This industry has 25 thousand tons per year of waste (i.e., shells) that mainly ends in landfills or at the bottom of the sea, thereby producing an ... -
Comparing circulating fluidised bed fly ash and limestone as additions for cement
(Emerald Publishing, 2019)[Abstract:] Circulating fluidized bed combustion (CFBC) power plants produce as by-product large ash particles with elevated calcium content. They are not commonly accepted as addition for cement although presenting ... -
Complete stress-strain analysis of masonry prisms under compressive loading-unloading cycles through digital image correlation
(Elsevier, 2024)[Abstract:] This paper presents the findings of an experimental study focused on the behaviour of masonry structures subjected to uniaxial loading-unloading compression. The study's primary objective is to examine the ... -
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 ... -
Constitutive behaviour of masonry prisms using a full-field measurement technique
(Elsevier, 2022)[Abstract:] To obtain analytical models for the compressive behaviour of masonry structures, it is crucial to accurately measure the compressive strengths of its constituents, i.e., brick and mortar. The mechanical properties ...
