EN 12190:1998

Overview

EN 12190:1998 - published by CEN - defines a standardized test method for determining compressive strength of repair mortar used in the protection and repair of concrete structures. The standard covers both structural and non‑structural repair materials as defined in EN 1504‑1, and applies to all types of repair mortar and repair concrete with a maximum aggregate size of 8 mm. EN 12190 distinguishes between mortars with hydraulic and polymer binders. In the standard, the term “mortar” is used to include both mortars and small‑aggregate concretes.

Key topics and requirements

• Scope and definitions
  • Applies to repair mortars/concretes for concrete repair, for both structural and non‑structural applications.
  • References EN 1504‑1 for material classification and intended uses.
• Material coverage
  • All repair mortar types, including hydraulic‑binder and polymer‑binder formulations.
  • Maximum aggregate size limited to 8 mm.
• Test objective
  • Establishes a reproducible method to determine compressive strength, a primary mechanical property used to assess performance and conformity.
• Test consistency
  • Standardizes specimen definition, conditioning and testing approach to enable comparable compressive strength results across laboratories and manufacturers.
• Terminology
  • Clarifies that “mortar” in this context includes small‑aggregate concretes used for repair.

(EN 12190 does not specify performance thresholds - it defines the test method; performance requirements are found in product standards and specifications like EN 1504 series.)

Practical applications

• Quality control and production
  • Manufacturers use EN 12190 compressive strength results to monitor batch consistency and to document product performance for technical data sheets.
• Product development and R&D
  • Material scientists and formulation engineers apply the test during development to optimize binder types and aggregate grading for targeted compressive strength.
• Specification and compliance
  • Specifiers and design engineers reference EN 12190 test results when verifying compliance with EN 1504‑1 system requirements or contract performance criteria.
• Contractors and testing laboratories
  • Construction contractors and independent testing labs perform EN 12190 tests as part of acceptance testing for repair works and certification processes.

Who should use this standard

• Manufacturers of repair mortars and small‑aggregate repair concretes
• Third‑party testing laboratories and certification bodies
• Structural engineers, specifiers and contract managers involved in concrete repair
• R&D teams developing repair materials
