    Traditional Coatings as Protection of Portland Cement Concrete Against Carbonation

    Abstract

    Reinforced concrete is usually subjected to carbonation attack. Although it is a slow
    development pathology, the consequences can be high, precisely in the places with greater
    human, residential or industrial occupation. To make matters worse, carbon dioxide
    concentration in the atmosphere has been increasing due to the impact of climate changes and
    also to the growth of number of large cities. One of the ways to increase the resistance to
    carbonation attack may be through the application of concrete coatings. In fact, many current
    constructions have a protective skin on the concrete, often ignored in the durability design
    project. For these reasons, this research has looked into the efficiency of the coatings when
    applied on concrete. Priority was given to traditional unpainted coatings, with cementitious
    base, hydrated lime or both. A coating based on fly ash and a thin coating of cement were also
    tested. All of them were applied in an ordinary Portland cement concrete. Accelerated
    carbonation tests were performed and the results were excellent. It was observed that the
    performance of the coated concretes was, on average, about 65% better when compared to the
    uncoated concrete.
