Testing
Designer
- Establish that in-situ concrete element achieves the required properties
- Specify level of testing required on site:
- Fresh concrete
- Hardened concrete
- Testing of concrete in final structure /element in case of doubt:
- e.g. cover to reinforcement, strength (cores)
Builder
- Facilities for storage of cubes, tank, temperature control, testing equipment, etc.
- Tests on fresh concrete to establish compliance with specification
- E.g. Consistence, air content etc.
- Tests on hardened concrete to establish compliance with specification
- E.g. Cube strengths
- Compare results to compliance criteria in Standard
- In-situ testing – Cores, Rebound Hammer, Pull Out
- Is audit supplier’s batching plant required
Producer
- Routine testing to demonstrate conformity with Standard
- For fresh concrete – slump testing
- For hardened concrete – cube testing
- Analysis to show conformity
- Testing required for development of project specific mixes
