Avaliação da resistência característica a compressão em estruturas de concreto a partir de ensaios não destrutivos

Abstract

This work analyzes the compressive strengths through quantitative and comparative analyzes between destructive and non-destructive tests in the evaluation of reinforced concrete structures. Such an approach is justified by the fact that the safety and performance of a structure are aspects relevant to structural behavior, which require validated and reliable techniques for decision making in engineering projects. This work ratified the efficiency of the experimental ultrasonography technique to evaluate the strength of structuresin reinforced concrete, by means of an analysis of the results obtained a dispersion in terms related to the average value of 6% (coefficient of variation), information that can be used in project decision making.
