Frequently asked questions
What is an NF aggregate for concrete?
An NF aggregate for concrete is an aggregate certified compliant with the NF P 18-545 standard by AFNOR Certification, an independent third-party body. The certification guarantees production regularity, traceability and compliance with the technical specifications for the production of concrete compliant with the NF EN 206 standard.
What is the difference between NF and CE 2+?
CE 2+ marking is a mandatory European regulatory requirement (standard EN 12620+A1). NF certification is voluntary and more demanding: it imposes external control by AFNOR, enhanced traceability and regular audits. MCA concrete aggregates are both CE 2+ and NF — you benefit from the best of both markings.
Which gradings does MCA offer in NF?
MCA offers 4 NF-certified gradings at the Warcq site: 0/4 mm (tertiary washed sand), 4/10 mm, 4/14 mm and 4/20 mm (tertiary washed gravels). All suited to concrete mix design.
