Abstract:
Several formulas have been derived from underlying equations for relationships between static and dynamic moduli of elasticity, for relationships between flexural and compressive strengths, etc., of hardened concretes method of derivation is based on the differing effect porosity in concrete on its mechanical properties. The derived formulas are new, and experimental, support them quite well. However, more important is applied method of derivation because it seems enough, even in its present simplified form, to provide improved relationships between mechanical properties hardened concrete. The fundamental advantage of the outlined metthod development is that it is mathematical as compared to purely empirical nature of the presently used method Also, it provides formulas that are valid both for weight and normal weight concretes.
