ANÁLISE DA PATOLOGIA DE ADERÊNCIA DOS REVESTIMENTOS ARGAMASSADOS: ESTUDO DE CASO - PROBLEMAS E POSSÍVEL SOLUÇÃO

Abstract

The present work is directed to a very area used in the construction in brazil, that of the morrown coatings applied on concrete surfaces. The case study aims to analyze the low-resistance pathology of adhesion to the tensile strength of morroted ceilings on the concrete surfasse, seeking to verify possible causes and a viable solution. As methodology was performed a literature review and after a case study of a located in the city of porto alegre – rs, where the pathology of the adhesion failure in an internal morroasted coating applied on the surfasse of concrete in ceilings. For this, adherence resistance tests were performed to in the coating, pre-and post-application of the magnesium floursilicate product, being possible to affirm that the product was effective for this case, because in the non-use the product was obtained a mean resistance of 0.29 mpa samples and after the the mean resistance of the samples was increased to 0.37 mpa.
