For ... -
Design and properties of cement coating with mussel shell fine aggregate
Martínez-García, Carolina; González-Fonteboa, Belén; Carro-López, Diego; Martínez-Abella, Fernando (Elsevier, 2019)[Abstract:] The production of farmed mussels amounts to millions of tonnes across over 40 countries. Shell waste resulting from this production has a very significant environmental impact. In Galicia, mussel shell waste ... -
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.
