@JournalArticle {2169, title = {Durability Indicators Comparison for SCC and CC in Tropical Coastal Environments}, journal = {Materials}, volume = {8}, year = {2015}, month = {2015-03-27 00:00:00}, pages = {1459-1481}, edition = {MDPI}, abstract = {Self-compacting concrete (SCC) demands more studies of durability at higher temperatures when subjected to more aggressive environments in comparison to the conventional vibrated concrete (CC). This work aims at presenting results of durability indicators of SCC and CC, having the same water/binder relations and constituents. The applied methodologies were electrical resistivity, diffusion of chloride ions and accelerated carbonation experiments, among others, such as microstructure study, scanning electron microscope and microtomography experiments. The tests were performed in a research laboratory and at a construction site of the Pernambuco Arena. The obtained results shows that the SCC presents an average electrical resistivity 11.4\% higher than CC; the average chloride ions diffusion was 63.3\% of the CC; the average accelerated carbonation penetration was 45.8\% of the CC; and the average open porosity was 55.6\% of the CC. As the results demonstrated, the SCC can be more durable than CC, which contributes to elucidate the aspects related to its durability and consequent prolonged life cycle.
