Can mussel shell waste optimize cement and air lime mortars hygrothermal performance?
Martínez-García, Carolina; González-Fonteboa, Belén; Carro-López, Diego; Faria, Paulina (Elsevier, 2024-10-23)[Abstract]: Mussel shells used as aggregates for mortars have flaky and irregular particles, which significantly increases the pore volume. This leads to the identification the microstructure of mussel shell mortars as a ... -
Carbonation evolution of lime putty coatings with mussel shell aggregate
Martínez-García, Carolina; González-Fonteboa, Belén; Carro-López, Diego; Martínez-Abella, Fernando (Elsevier, 2020)[Abstract:] The carbonation process is studied from young ages up to 2 years in mortars with fine mussel shell aggregate. Mussel shell aggregate affects lime mortars due to its shape (angular and flaky) and texture (smooth), ... -
Characterization of concrete behavior under cyclic loading using 2D digital image correlation
Bello, Ismail; González-Fonteboa, Belén; Wardeh, George; Martínez-Abella, Fernando (Elsevier, 2023)[Abstract:] The development of plastic deformations of concrete during loading-unloading cycles and post-cracking behavior must be carefully controlled for accurate modeling of concrete structures. This study aims to ... -
Characterization of mussel shells as a bio-based building insulation material
Martínez-García, Carolina; González-Fonteboa, Belén; Carro-López, Diego; Martínez-Abella, Fernando; Pérez Ordóñez, Juan Luis (Association universitaire de génie civil, 2019-06-26)[Abstract]: In Galicia, 35% of mussel culture is intended for canning. This industry has 25 thousand tons per year of waste (i.e., shells) that mainly ends in landfills or at the bottom of the sea, thereby producing an ... -
Comparing circulating fluidised bed fly ash and limestone as additions for cement
Carro-López, Diego; González-Fonteboa, Belén; Eiras López, Javier; Seara Paz, Sindy (Emerald Publishing, 2019)[Abstract:] Circulating fluidized bed combustion (CFBC) power plants produce as by-product large ash particles with elevated calcium content. They are not commonly accepted as addition for cement although presenting ... -
