1 Scope
The document specifies a method to determine the static elastic modulus of natural stone in uniaxial compression.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated references,
only the edition cited applies. For undated references, the latest edition of the referenced document (including any
amendments) applies.
EN 1926, Natural stone test methods – Determination of compressive strength
EN 12390-4, Testing hardened concrete – Part 4: Compressive strength – Specification for testing machines
3 Principle
The longitudinal deformations of a specimen under basic and upper uniaxial compressive stresses are measured.
From these values the static elastic modulus is calculated.
4 Symbols and definitions
E static elastic modulus in Megapascals (MPa);
b
