Análise comparativa da influência das variáveis: geometria e tipos de regularização de faces, nos resultados dos ensaios de compressão axial

Abstract

One of the parameters most used for the classification of the concrete is its resistance to compression. However, the resistance test may have its outcome influenced by several factors, such as the geometry and the type of regularization of its faces. In the literature there are different studies on the influence of geometry and the type of regularization, however, little is studied about these two variables together. The present research presents by means of experiments and data analysis the technique that showed less interference on the samples analyzed. The present research used the two types of geometry for most used specimens: cylindrical and cubic, along with the three techniques of regularization of faces most commonly used: sulfur, elastomeric pads and grinding in the two classes of resistances used. By analyzing the results and seeking greater reliability and precision in the values obtained in the technological control trials, it was observed that the arrangement that least interfered in the results was the combination of cylindrical test specimens using neoprene as a regularization technique, for both classes of resistance studied.
