Assessment of the permeability to aggressive agents of concrete with recycled cement and mixed recycled aggregate
Cantero, B.; Bravo, Miguel; de Brito, J; Sáez del Bosque, Isabel F.; Medina Martínez, César (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 ... -
Durability of Eco-Efficient Binary Cement Mortars Based on Ichu Ash: Effect on Carbonation and Chloride Resistance
Caneda-Martínez, Laura; Frías, Moisés; Sánchez Montero, Javier; Rebolledo, Nuria; Flores, Elena; Medina Martínez, César (Elsevier, 2022)[Abstract] This research work focuses on the performance of mortars containing ichu ash as a potential environmentally-sound alternative to traditional pozzolans (at 6% and 10% replacement levels) under CO2 and chloride ... -
Resonance fatigue behaviour of concretes with recycled cement and aggregate
Cantero, B.; Sainz-Aja, José Adolfo; Yoris, Adrian; Medina Martínez, César; Thomas, Carlos (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 ... -
The Influence of Fly Ash on the Mechanical Performance of Cementitious Materials Produced with Recycled Cement
Cantero, B.; Bravo, Miguel; de Brito, J; Sáez del Bosque, Isabel F.; Medina Martínez, César (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
Sequeira, Lucas; Cantero, B.; Bravo, Miguel; de Brito, J; Medina Martínez, César (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
Cantero, B.; Bravo, Miguel; de Brito, J; Sáez del Bosque, Isabel F.; Medina Martínez, César (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 ...
