dc.description.abstract | In recent years, growing interest has focused on determining the performance of materials and evaluating
the service life of structures exposed to various environmental forces. In this context, the determination
of the aggressive potential of marine salts on mortars used as external renders is critical. The
present study aimed to evaluate the spatial distribution of marine salts relative to distance from the sea.
This was done by monitoring the deposition rate of chlorides and sulfates in wet candle sensors, located
at nine stations scattered around the Metropolitan Region of Salvador, state of Bahia, Brazil. The study
also determined the effectiveness of water-soluble salts at penetrating three different types of mortars of
varying cement content via deposition and diffusion. The methodology employed enabled an evaluation
of the efficiency of the monitoring sensors’ measurement of the aggressiveness potential of local marine
aerosol, and determination of the comparative performance of the three mortars tested, from the
standpoint of resistance to salt penetration. The type and amount of salts captured both in solution and
in powder samples extracted from the mortars were determined by ion chromatography. The analysis of
the various types of mortars tested indicated which types are more resistant to the aggressive potential
of the region’s marine aerosol and the distance from the shore where local buildings are liable to be most
strongly affected. | pt_BR |
