INFLUÊNCIA DE MATERIAIS DE PROTEÇÃO SUPERCIAL NA RESISTIVIDADE ELÉTRICA E ABSORÇÃO CAPILAR DO CONCRETO
(Universidade Federal de Santa Maria, 2011-01-24)
The durability of concrete structures is the result of protective action of concrete over the rebar. When the passivation of steel ceases to exist the structure becomes vulnerable to the phenomenon of corrosion, which ...
RESISTIVIDADE ELÉTRICA DE CONCRETOS DE CIMENTO PORTLAND BRANCO E ELEVADOS TEORES DE ESCÓRIA DE ALTO FORNO
(Universidade Federal de Santa Maria, 2008-03-03)
The electrical resistivity is an important concrete property that allows evaluating the access facility of aggressive agents before the corrosion process begins and estimates the velocity of the same process after it begun. ...
RESISTIVIDADE ELÉTRICA DE CONCRETOS CONTENDO DIFERENTES TEORES DE CINZA DE CASCA DE ARROZ
(Universidade Federal de Santa Maria, 2005-10-21)
The durability of reinforced concrete structures derives from the protective effect provided by the concrete cover over the steel rebars. When the passivation of the steel is compromised, the whole structure is liable to ...
RESISTIVIDADE ELÉTRICA DE CONCRETOS COM DIFERENTES TEORES DE ESCÓRIA DE ALTO FORNO E ATIVADOR QUIMICO
(Universidade Federal de Santa Maria, 2005-12-15)
The integrity of the rebars in reinforced concrete structures is related to the chemical and physical protection provided by the concrete layer that covers the steel. The destruction of the passivation layer precedes the ...
