Comparing circulating fluidised bed fly ash and limestone as additions for cement
(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 ... -
Masonry and render mortars with tyre rubber as aggregate: Fresh state rheology and hardened state performances
(Elsevier, 2020)[Abstract:] This work shows how it is possible to tailor cement-rubber composites suitable as renders and masonry mortars with a reduced liquid water absorption. Recycled tyre rubber is used as aggregate in mixture with ... -
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) ...
