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 ... -
Deformation Recovery of Reinforced Concrete Beams Made With Recycled Coarse Aggregates
Seara Paz, Sindy; González-Fonteboa, Belén; Martínez-Abella, Fernando; Eiras López, Javier (Elsevier, 2022)[Abstract] The purpose of this research is to analyse the long-term deformations of reinforced concrete beams made of recycled coarse aggregates (RCA), using four different replacement ratios, 0%, 20%, 50% and 100%. For ... -
Effects of bacteria-based self-healing nutrients on hydration and rheology of cement pastes
Pinto, Adonay; González-Fonteboa, Belén; Seara Paz, Sindy; Martínez-Abella, Fernando (Elsevier, 2023)[Abstract:] Crack openings in concrete lead to a reduction in its lifespan. Many authors have analysed different techniques that could repair cracks autonomously, being the use of bacteria one of the most promising approaches. ... -
Estimating Adaptive Setpoint Temperatures Using Weather Stations
Bienvenido Huertas, José David; Rubio-Bellido, Carlos; Pérez Ordóñez, Juan Luis; Martínez-Abella, Fernando (MDPI, 2019)[Abstract] Reducing both the energy consumption and CO2 emissions of buildings is nowadays one of the main objectives of society. The use of heating and cooling equipment is among the main causes of energy consumption. ... -
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 ... -
Influence of the Mixing Procedure on the Fresh State Behaviour of Recycled Mortars
González-Fonteboa, Belén; González-Taboada, Iris; Carro-López, Diego; Martínez-Abella, Fernando (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 ... -
Mussel shell mortars durability: Study of aggregate replacement limit
Martínez-García, Carolina; González-Fonteboa, Belén; Carro-López, Diego; Martínez-Abella, Fernando (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 ... -
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 ... -
Recycled concrete with coarse recycled aggregate. An overview and analysis
González-Fonteboa, Belén; Seara Paz, Sindy; de Brito, J; González-Taboada, Iris; Martínez-Abella, Fernando; Silva, Rui (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, ... -
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 ...
