Desenvolvimento de um compressômetro para determinação do módulo de elasticidade do concreto

Abstract

The determination of the mechanical properties of the concrete is of autmost importance to be scaled a concrete structure. Thus, most of the structural designs are calculated based on compressive strength, which is determined by compression tests, but for calculating structural approach in a more realistic behavior of the material is of great importance to study the deformation properties of the material to be used, not only the compressive strength, but also to know the exact modulus of elasticity. The measure of deformation is the most important factor to determine the elastic modulus and then it was designed and constructed a compressômetro for measuring the deformation of a cylindrical specimen of concrete during the compression test. During the work was performed the following steps: three-dimensional modeling software in the compressômetro-3D CAD (Design Three Dimensional Computer Aided); manufacture; performing compression tests of specimens of concrete aided compressômetro and analyzes the results to see if the device is able to be constructed approved. The results showed a good correlation with the empirical formula of NB1 and thus the compressômetro was approved.
