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 ... -
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 ... -
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 ... -
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), ... -
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 ... -
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) ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
Waste-Based Porous Materials as Water Reservoirs for the Internal Curing of Concrete. A Review
(Elsevier, 2021)[Abstract] This review collates findings from more than 100 scientific publications regarding the performance of several waste-based porous materials (WASPORs) as water reservoirs for the internal curing of concrete. Results ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
