Overview
EN 679:2005 is the CEN (European) standard that specifies a standardized procedure for the determination of the compressive strength of autoclaved aerated concrete (AAC). It defines sampling, specimen preparation, conditioning, test apparatus, loading procedure and how to calculate and report compressive strength results for AAC products.
Key topics and technical requirements
- Scope: Applies to measuring axial compressive strength of AAC (autoclaved aerated concrete) test specimens.
- Test specimen: Cubes of 100 mm edge length are specified; alternative sizes allowed only if results can be directly related to 100 mm cubes. A test set = three specimens (ideally sampled from upper, middle and lower thirds relative to the direction of rise).
- Apparatus: Saw for cutting, compression testing machine meeting EN 12390-4 (machine class 1 or 2), calipers (0.1 mm accuracy), ventilated oven (105 ± 5 °C), straight edge/feeler gauges, balance (0.1 % accuracy).
- Dimensional tolerances: Planeness of load surfaces ≤ 0.1 mm; right-angle deviation ≤ 1 mm/100 mm.
- Conditioning & moisture control: Specimens conditioned to a moisture content of (6 ± 2) % by mass at ≤ 60 °C, then equilibrated at (20 ± 5) °C for at least 2 h before testing.
- Loading procedure: Axial load applied perpendicular to direction of rise at a constant stress rate of 0.1 ± 0.05 MPa/s until rupture; record maximum load.
- Calculations: Individual compressive strength fci = Fi / Aci (N / mm²). Product strength fc = mean of three specimens. Individual values rounded to 0.05 MPa, product to 0.1 MPa.
- Post-test drying: After failure, specimens are dried at (105 ± 5) °C to determine actual moisture content (EN 1353) and dry density (EN 678). Procedures for lost material/volume are provided.
- Test report requirements: Product ID, manufacture date, test location, standard reference, specimen geometry and positions, moisture content, dry density, individual and mean compressive strengths, and visual observations.

EN 679:2005 is used for:
- Quality control in AAC manufacturing - routine strength verification of blocks and prefabricated components.
- Product certification and compliance with European product standards.
- Test laboratories performing material characterization for suppliers and specifiers.
- Design and procurement teams needing standardized compressive strength data for specification and acceptance.
