Durability Of Concrete

RESUMOA durabilidade das estruturas de concreto armado é resultado da ação protetora do concreto sobre a armadura. Quando a passivação do aço deixa de existir a estrutura torna-se vulnerável ao fenômeno da corrosão, cuja propagação, após iniciada é essencialmente controlada pela resistividade elétrica do concreto. O objetivo deste trabalho foi avaliar a alteração na resistividade elétrica de concretos produzidos com diferentes tipos de cimento, CP II F, CP IV e CP V, submetidos a tratamento superficial com produto obturador dos poros e argamassa polimérica. Para efeito de análise os resultados foram comparados com os mesmos concretos sem aplicação do produto. Esses tratamentos foram realizados em concretos confeccionados com resistências à compressão na idade de 28 dias de 21,6MPa, 26,6 MPa e 31,6 MPa. Para todos os tipos de cimento utilizados e níveis de resistência adotados o tratamento superficial com argamassa polimérica resultou em maiores valores de resistividade elétrica.Palavras chave: Concreto; durabilidade; material de proteção superficial; resistividade elétrica.ABSTRACTThe durability of concrete structures is a result of the protective action of concrete on the reinforcement. When there is no passivation of steel, the structure becomes vulnerable to corrosion, and once corrosion starts its propagation is essentially controlled by the electrical resistivity of concrete. The objective of this study was to evaluate the change in electrical resistivity of concretes produced with different types of cement: CP II F, CP IV and CP V that were surface-treated with pore filler and polymer mortar. For analysis purposes, the results were compared with those of the blanks that were not subjected to surface treatment. These treatments were performed in concretes with the following compressive strengths at the age of 28 days: 21.6 MPa, 26.6 MPa and 31.6 MPa. For all types of cement used and strengths adopted, surface treatment with polymer mortar led to higher electrical resistivity values.Key words: Concrete; durability; surface protection material; electrical resistivity.
