The Effect of Eccentricity of Concrete Specimen on Measured Value of Modulus of Elasticity

Abstract:

The measurement of the modulus of elasticity is a technologically demanding test and its correct implementation has a fundamental effect on the resulting measured value. The main influences that may affect the proper performance of the test include, for example, the shape and size of the test specimen, the method of obtaining the test specimen, the method of adjustment of contact area between specimen and hydraulic equipment, but also the eccentricity of the specimen in the test apparatus. The paper presents the results of an experiment focused on the influence of the eccentricity of the test specimen and the observance of standard measurement conditions. The standard determines the maximum strain difference on individual measuring sensors when the maximum test force is reached.
