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 com diferentes teores de escória de alto forno e ativador químico
(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 ...
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 ...
