Experimental selection of young's modulus according the structure of concrete

[摘要] The article provides an overview of the dependencies connecting structure of concrete with young's modulus. The developed method experimental evaluation of the known dependencies. In the studies used samples with different number and different size of crushed stone. Shows the compositions of the used concretes. According to the results of the tests were obtained the theoretical diagrams of the concrete. The paper presents the results of experimental studies of various compositions of concrete. Part of the dependency of the young's modulus was checked for consistency with experimental data. Proposed practical methodology for the evaluation of the concrete structure. According to the results of the comparison proposed a theoretical model for the estimation of the young's modulus for concrete structures.
