1 Verein Deutscher Zementwerke e.v. Research Institute of the Cement Industry VDZ- portfolio Concrete and mortar Synergies gained from current research and expertise

2 VDZ-service portfolio Concrete and mortar Synergies gained from current research and expertise For more than 125 years the Verein Deutscher Zementwerke e.v. (VDZ) has been contributing with its research both to competitive and environmentally compatible cement production and to the development of high-quality concrete constructions. Our interdisciplinary team is available to you, offering consulting and state-of-the art expert advisory services regarding the production of concrete and mortar. VDZ and its Research Institute offer the complete range of services starting from all established test methods as well as advisory services up to complex expert s reports. The combination of state-of-the-art research and competent services results in synergies which are reflected in a high quality and practical relevance of our work. In the field of concrete and mortar we offer research and services regarding current issues with respect to concrete components as well as concrete technology and application. The present summary of our service-portfolio provides you with an overview of our service range. Testing of fresh concrete and fresh mortar see para. 1 Testing of hardened concrete and hardened mortar see para. 2 Durability testing see para. 3 Testing of aggregates see para. 4 Testing of admixtures see para. 5 Testing of shrinkage in concrete see para. 6 Supervision of the placing of concrete on construction sites (supervision class 2 and 3) see para. 7 Certification of buildings with regard to sustainability (DGNB certification system) see para. 8 Suitability test of injection mortar for tendons Development of concrete and mortar mixes on request of customers (e.g. for self-compacting concrete, ultra-high performance concrete, etc.) Assessment procedure to obtain general approvals issued by the DIBt, European Technical Approvals (ETA) and KOMO-attests with product certificates in accordance with CUR 48
