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
(MDPI, 2023)[Abstract:] In the construction industry, cement is the most widely used material. So, to achieve greater sustainability in this industry, it is imperative to improve the sustainability of this material. One way to reduce ... -
Thermal performance of concrete with recycled concrete powder as partial cement replacement and recycled CDW aggregate
(MDPI, 2020)[Abstract:] This novel study was triggered by a lack in the international literature of the simultaneous use of ground recycled concrete (GRC) as a cement replacement and mixed recycled aggregate as part of the granular ... -
Thixotropy and interlayer bond strength of self-compacting recycled concrete
(Elsevier, 2018)[Abstract:] This work is focused on assessing the thixotropy of self-compacting recycled concrete (SCRC) and on evaluating the interlayer bond strength. To do so, four SCRC mixes with 0%, 20%, 50%, and 100% of recycled ... -
Ultimate Capacity of Corroded Statically Indeterminate Reinforced Concrete Members
(Springer, 2018)[Abstract:] The corrosion of steel reinforcement is commonly believed to be the primary cause of structural deterioration of reinforced concrete (RC) structures; as a result of this deterioration, a RC structure can incur ... -
Use of granular coal combustion products as aggregates in structural concrete: Effects on properties and recommendations regarding mix design
(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 ... -
