Currently, concrete is the most used material in civil construction for the most diverse types of constructions. Due to its importance for the area, more researches study about the physical and mechanical properties of the ...
Durabilidade de argamassas submetidas ao ataque de sulfatos : efeito da adição da nanosílica
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Civil - PPGECivCâmpus São Carlos, 2018-03-28)
Durability is one of the characteristics to be considered in design and projects of concrete structures as it is related to the useful life of buildings. Among the aggressive agents most damaging to the concrete are sulfate ...
Interactions in nanosilica-polyurethane composites evidenced by plate-plate rheology and DMTA
(Wiley, 2005-01)
Fumed nanosilicas with different degree of silanization were used to obtain nanosilica-polyurethane (TPU) composites to modify their rheological and mechanical properties. The higher the silanol content of the nanosilica, ...
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. ...
