Full title and description

Testing of concrete — Part 10: Determination of static modulus of elasticity in compression. This International Standard specifies a laboratory test method for determining the static (secant) modulus of elasticity in compression of hardened concrete, applicable to specimens cast specifically for testing or taken from structures.

Abstract

ISO 1920-10:2010 defines the procedure for measuring the static modulus of elasticity of hardened concrete in compression, including specimen conditioning, loading and unloading cycles, strain measurement and calculation of the modulus. The method yields the secant (static) modulus used for design verification, structural assessment and material characterization.

Scope

ISO 1920-10:2010 applies to the determination of the static modulus of elasticity in compression of hardened concrete. It covers requirements for test specimens (cast or cored), conditioning, the loading and unloading procedure for the compression test, the measurement of axial strain (by extensometers, strain gauges or equivalent devices) and the calculation and reporting of the static (secant) modulus. The method is intended for use in laboratory and on-site testing where verification of elastic properties of concrete is required.

Key topics and requirements

• Definition and scope: static (secant) modulus of elasticity in compression of hardened concrete.
• Specimen types and preparation: standard specimen sizes or cores taken from structures, conditioning to specified moisture/temperature states.
• Loading regime: prescribed loading/unloading cycles and loading rate for determining secant modulus.
• Strain measurement: use of calibrated extensometers, strain gauges or equivalent devices and their placement/accuracy requirements.
• Calculation: method to calculate static (secant) modulus from measured stress–strain data and reporting conventions.
• Reporting: required information for test reports (specimen details, conditioning, equipment, test results and any deviations).

Typical use and users

Typical users are materials testing laboratories, university and research laboratories, structural and geotechnical engineers, quality assurance personnel, contractors and standards bodies. The standard is used when elastic properties of hardened concrete are required for structural design checks, finite-element modelling, assessment of existing structures or verification of material conformity.
