Artigo Científico Acesso aberto Análise da resistência à tração de argamassa de revestimento em substrato de concreto: estudo de caso(2020) Bertuol, Mateus RodolfiThis article presents a proposal with different types of roughcast on the market to solve the problem of detachment of ceiling covering, which occurred in a multifamily residential located in São José / SC, since the traditional roughcast produced on site caused the lack of adhesion of the coating on concrete substrate. To test the adherence capacity of the coating, the resistance test is carried out, the main technological control of mortar coatings, standardized by NBR 13528: 2010. The work matrix was composed of two types of roughcast, rolled and industrialized, applied on concrete substrate. The test with these types of roughcast was performed as a proposal to solve the problem and the roughcast that showed greater efficiency in the tests in the rest of the residential was used. The tests were carried out on the ceiling covering of two rooms. In both rooms the lining structure had a single layer and the lining line had the same characteristics. It was observed that, in general, the best results that met the minimum limit of adhesion resistance to traction, according to the standard NBR 13749: 2013, were the results of the test carried out on the industrialized roughcast.
