Opredelenie modulya uprugosti betona ul'trazvukom
Determination of modulus of elasticity of concrete by ultrasonic method used for axially compressed and tensile concrete prisms, and reinforced concrete members with seven-wire steel strands under axial tension; initial dynamic and static moduli of elasticity of prestressed specimens are higher than in concrete prisms; average coefficient of transition from dynamic to static modulus of elasticity of concrete prisms and of prestressed reinforced concrete specimens is 0.95.
