Electrodynamic technique for the measurement of the elasticity module of the building materials. (Equipment fitted in IETcc for the measurement of the dynamic module of elasticity)

Abstract

This work can be devided into two parts. The first considers the utility of the measurement of the dynamic module of elasticity of the building materials; it also contains an introduction to the elastic performances of the materials particularly of the concrete. Part two includes a revision of the test method established by the standards mostly used for the measurement of this characteristic, a description of the equipment recently adopted by the lETcc for this purpose, where the changes are pointed out, as well as the study carried out four the fitting, including the repeatability of test results. The work includes the following paragraphs^ 1. - Introduction. 2. - The concrete as an elastic material. 3. - Measurement of the elastic characteristics of the concrete. 4. - Electrodynamic method for the measurement of the elasticity module of the building materials. 4.1. - Method base. 4.2. - Test process. 4.3. - lETcc equipment for the measurement of the elasticity module. 4.4. - Setting of the equipment. 4.5. - Operative method. 4.6. - Calculation of the dynamic elasticites module. 4.7. - Results repeatability. 5. - Conclusions. 6. - Acknowledgements. 7. - Bibliography.
