Certification of cements and other binders


The quality inspection and development of quality standards have been one of VDZ's founding tasks for more than 140 years. Today, the monitoring and certification body of VDZ monitors and certifies more than 500 binders in 60 cement works. The "VDZ hexagon" has stood for the highest quality standards for many decades. It's no coincidence that our seal can be found today on almost all the cements sold in Germany.
