Alkali-activated slag concrete: Fresh and hardened behaviour
Puertas, Francisca; González-Fonteboa, Belén; González-Taboada, Iris; Alonso López, María del Mar; Torres Carrasco, Manuel; Rojo-López, Gemma; Martínez-Abella, Fernando (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, ... -
Automated Control of the Fresh State of Industrial Concrete Behaviour by Rheometer Test Adjustment
Rojo-López, Gemma; González-Fonteboa, Belén; Carro-López, Diego; Martínez-Abella, Fernando (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 ... -
Genetic programming to understand the influence of new sustainable powder materials in the fresh performance of cement pastes
Rojo-López, Gemma; González-Fonteboa, Belén; Pérez Ordóñez, Juan Luis; Martínez-Abella, Fernando (Elsevier, 2024)[Abstract:] This study focused on pastes that incorporate metakaolin, biomass ash, and granite powder as supplementary cementitious materials to obtain specific expressions to predict rheological properties in pastes and ... -
Influencia de las variaciones en los materiales sobre la reología de hormigones autocompactantes reciclados
González-Taboada, Iris; González-Fonteboa, Belén; Martínez-Abella, Fernando; Rojo-López, Gemma (Universitat Politècnica de València UPV, 2018)[Resumen:] Este trabajo se centra en el análisis de la influencia de las variaciones de materiales sobre el comportamiento reológico de los hormigones autocompactantes fabricados con árido grueso reciclado. Se diseña un ... -
Parametric Analysis in Sustainable Self-Compacting Mortars Using Genetic Programming
Rojo-López, Gemma; González-Fonteboa, Belén; Pérez Ordóñez, Juan Luis; Martínez-Abella, Fernando (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 ... -
Quaternary blends of portland cement, metakaolin, biomass ash and granite powder for production of self-compacting concrete
Rojo-López, Gemma; Nunes, Sandra; González-Fonteboa, Belén; Martínez-Abella, Fernando (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) ... -
Research and New Smart Techniques on the Characterisation of New Self-compacting Concrete with Industrial Wastes and Fibres to Increase its Sustainability and Service Life
Rojo-López, Gemma (2024)[Resumo] Este traballo aborda o desenvolvemento de mesturas autocompactantes coa incorporación de materiais suplementarios procedentes de residuos industriais como substitutos de cemento para aumentar a sustentabilidade, ... -
Rheology, Durability, and Mechanical Performance of Sustainable Self-Compacting Concrete With Metakaolin and Limestone Filler
Rojo-López, Gemma; González-Fonteboa, Belén; Martínez-Abella, Fernando; González-Taboada, Iris (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 ...
