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. ... -
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 ... -
