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, ... -
Masonry and render mortars with tyre rubber as aggregate: Fresh state rheology and hardened state performances
(Elsevier, 2020)[Abstract:] This work shows how it is possible to tailor cement-rubber composites suitable as renders and masonry mortars with a reduced liquid water absorption. Recycled tyre rubber is used as aggregate in mixture with ... -
Masonry Mortars, Precast Concrete and Masonry Units Using Coal Bottom Ash as a Partial Replacement for Conventional Aggregates
(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 ... -
Mechanical and microstructural properties of high-performance concrete made with rice husk ash internally cured with superabsorbent polymers
(CellPress, 2022)[Abstract:] An experimental study was carried out to determine the properties of rice husk ash (RHA) and its effect on high-performance concrete's (HPC) mechanical and microstructural properties. RHA content was placed at ... -
Mussel shell mortars durability: Study of aggregate replacement limit
(Elsevier, 2023-12-12)[Abstract]: The knowledge acquired through previous experimental phases with coating mortars with mussel shell aggregates led to conclude that irregular, flaky and hydrophobic particles of the mussel shell and the organic ... -
Mussel shells: A canning industry by-product converted into a bio-based insulation material
(Elsevier, 2020)[Abstract:] The canning industry in Galicia produces 25 thousand tonnes of mussel by-product (i.e. unconsumed shells) per year, having a significant environmental impact. Mussel shell becomes suitable for different uses ... -
Parametric Analysis in Sustainable Self-Compacting Mortars Using Genetic Programming
(Elsevier, 2023-09-06)[Abstract]: This study addresses the capabilities of genetic programming to predict the behaviour of cement-based mixtures by focusing on the influence of quaternary binders (incorporating metakaolin, biomass ash and granite ... -
Physical and hydraulic properties of porous concrete
(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 ... -
Quaternary blends of portland cement, metakaolin, biomass ash and granite powder for production of self-compacting concrete
(Elsevier, 2020)[Abstract:] Given the rising societal pressure towards sustainable waste management and resource efficiency, in a more circular economy, an increased use and diversification of supplementary cementitious materials (SCM) ... -
Recycled concrete with coarse recycled aggregate. An overview and analysis
(CSIC, 2018)[Abstract:] The construction field has contributed to environmental degradation, producing a high amount of construction and demolition waste (C&D waste) and consuming large volumes of natural resources. In this context, ... -
Resonance fatigue behaviour of concretes with recycled cement and aggregate
(MDPI, 2021)[Abstract:] The huge increase in production of construction and demolition waste (CDW) worldwide is leading to the valorisation of as recycled aggregates. One of the most promising alternatives is its use as a recycled ... -
Rheology, Durability, and Mechanical Performance of Sustainable Self-Compacting Concrete With Metakaolin and Limestone Filler
(Elsevier, 2022)[Abstract] This study analyzed the performance of self-compacting concrete with a paste composition that includes limestone filler and metakaolin replacing cement to design binary (75% cement and 25% limestone filler) and ... -
Robustness of self-compacting recycled concrete: analysis of sensitivity parameters
(Springer, 2018)[Abstract:] This work is focused on understanding the origin of the lower robustness detected in self-compacting recycled concretes and on identifying the parameters affecting this property to a greater extent. A reference ... -
Study of Different Granular By-Products as Internal Curing Water Reservoirs in Concrete
(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 ... -
The Arousa Island bridge. Complete refurbishment and 10 years analysis description
(Wiley, 2024)[Abstract:] The Isla de Arousa Bridge, 1980 m long, is the only road access to Isla de Arousa. Built in 1985, this single-cell box girder divided into 40 spans runs entirely over the sea. In response to corrosion damage, ... -
The effect of recycled aggregates on the accuracy of the maturity method on vibrated and self-compacting concretes
(Elsevier, 2019)[Abstract:] Fine and coarse recycled aggregate used jointly as partial replacement of natural aggregate is not allowed for structural concrete in many international standards. More studies about it are needed toward more ... -
The Influence of Fly Ash on the Mechanical Performance of Cementitious Materials Produced with Recycled Cement
(MDPI, 2022)[Abstract:] Concrete is the most widely used construction material in the world; as such, the best way to promote a more sustainable construction industry is to improve the environmental performance of this material. Since ... -
The influence of recycled cement, fly ash, and magnesium oxide on the mechanical performance of sustainable cementitious materials
