Internally cured high performance concrete with magnesium based expansive agent using coal bottom ash particles as water reservoirs
(Elsevier, 2020)[Abstract:] Shrinkage is one of the main concerns related to high performance concrete (HPC) durability. Its high density paste, consequence of a low water to binder ratio, can be unprofitable if cracks appear due to ... -
Effects of mussel shell aggregates on hygric behaviour of air lime mortar at different ages
(Elsevier, 2020)[Abstract:] Mussel shells, composed of calcium carbonate (>95%) and organic matter, are suitable alternatives to conventional sand in mortar. In addition, the use of lime instead of cement as a binder has also been considered ... -
Quaternary blends of portland cement, metakaolin, biomass ash and granite powder for production of self-compacting concrete
(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) ... -
Mussel shells: A canning industry by-product converted into a bio-based insulation material
(Elsevier, 2020)[Abstract:] The canning industry in Galicia produces 25 thousand tonnes of mussel by-product (i.e. unconsumed shells) per year, having a significant environmental impact. Mussel shell becomes suitable for different uses ... -
Alkali-activated slag concrete: Fresh and hardened behaviour
(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, ...
