Influência da porosidade dos tijolos cerâmicos no surgimento de patologias devido a umidade ascendente

Abstract

This work aims to seal the ceramic bricks used in construction, for it should study the formation of pores therein, which occur during burning through high temperature, where the organic material present in the clay is eliminated by heat generating pores. Buildings that have waterproofing done badly or nonexistent are conducive to suffer rising water , this work is given greater emphasis capillarity phenomenon by which water travels in the soil pores of the materials used , causing conditions such as: mold , stains , efflorescence, rotting mortars and plasters . To prevent the building up of these diseases , are usually used in waterproofing asphalt based on the footing beams , but in this study the use of alternative materials for the brick has been proposed as D- limonene and polystyrene, in order to perform the sealing the same , giving greater security against pathological manifestations in buildings . Although the vacuum system originally proposed has not proved entirely satisfactory due to the viscosity of the mixture of D - limonene and Styrofoam, can be seen when the specimens were immersed in the same mixture, there was traces of plastic in the pores of bodies analyzed, proving that it is indeed possible to waterproof the bricks used in construction, although more studies are still needed about.
