Production control of construction material
Production of concrete and mortar are one of the main parts of sand and gravel year production.
To avoid health risks is the mean priority of building regulations.
To reach this target there are some specific norms in the EU. For example the EN 12620 (Aggregates for concrete) and the EN 13139 (Aggregates for mortar) apply.
For inspection of building materials the following parts are prescribed:
- factory production control by the manufacturer
- external quality control, by a accredited laboratory
- certification by a notified body
