Use of silica fume and nano-silica in mortars attacked by acids present in pig manure
(2018-01-01)
Pig houses provide a highly aggressive environment to concrete structures. The chemical aggressiveness generated by pig manure may cause wear, loss in strength and premature damage to floors, leading to animal hoof diseases. ...
Luminescent nano-composites generated from a spray
(Elsevier B.V., 2008-11-01)
The spray-pyrolysis (SP) synthesis technique has been employed to obtain SiO2:Eu3+ and gamma-AlOOH:Eu3+, It was possible to obtain sub-micrometric spherical particles of SiO2 with luminescent Eu3+ ions bonded to the silica ...
Eco-Concrete for Hydraulic Structures with Addition of Colloidal Nano-Silica
(Institute of Physics Publishing, 2020-02-28)
In the construction of buildings and infrastructures, high resistance materials are used due to current design requirements, concrete being one of the main materials used in the execution of these projects whose cement ...
Estudo da sinergia entre nano sílica e micro sílica em argamassas para aplicação em concretos como proposta de melhoria de desempenho
