The project objective is the development of new creep strain, in various stress-strain conditions, determination method, modification of necessary stands for testing, measurement detection approach depending on specimen’s shape for innovative structural cement composites which cannot be determined by existing standard methodologies and approbate them, obtaining long-term properties of these materials. Based on the obtained experimental data the new empirical predictive model for determination of long-term properties will be devolved.
During the project the actual values of the creep strains in various stress-strain conditions, the different strength values, and the moduli of elasticity of the new, innovative structural cement composites will be obtained in laboratory conditions, which cannot be determined with the existing standardized methodologies and models. These properties have not been researched for these materials before. For the determination of their properties the specimens with different age and different geometric shape will be used and the loading will be applied. The newly modified testing stands will be used for the determination of creep strains in various stress-strain conditions. A new approach of specimen geometry for the creep strain determination in various stress-strain conditions will be used. The new approach for determination of creep strain will be used. Based on experimental results the new empirical prediction model for new innovative cement composites long-term properties will be developed.
