Checking for chloride penetration in test samples partially immersed in seawater in Recife, Pernambuco State

The purpose of the study is to analyse, using chemical tests, the quantity of chloride ions in concretes with different traces (proportions of materials) in their depths. To do so, tests were performed in laboratories, and test samples were made with partial immersion in seawater, in accordance with the standards and Mohr method. The results confirmed that the penetration percentage of chloride ions is less for the rich trace, in relation to the others test samples studied. Accordingly, it is concluded that the stronger the concrete the greater the penetration resistance of chloride ions, but these results are to be expected, since the concrete with greatest strength and same materials tends to hinder the entry of those ions.
