AAC WORLDWIDE %u2022 2.2025 PRODUCTION TECHNOLOGY 79tion later in the factory. The Wehrhahn technical centre makes it possible to produce AAC in classic block dimensions (e.g. 600 mm x 200 mm x 150 mm). A 500 litre autoclave is used for the autoclaving process. The autoclave control system is exactly the same as that developed by Wehrhahn for large-scale production (WACO). This means that the entire cycle consisting of vacuum, pressure ramp-up, holding phase and controlled pressure release can be reproduced.The manufactured blocks are then tested for their physical properties in accordance with the applicable standards. Finally, the crystal structure is analysed in an X-ray diffractometric analysis (XRD). The quality and quantity of the formed tobermorite has a significant influence on the quality of the autoclaved aerated concrete.The laboratory specialists give the %u201cgreen light%u201d once all quality parameters have been met, and the customer can be sure of being able to produce excellent AAC. Incidentally, the same specialists are also on site during the commissioning of the plant and accompany the customer until the plant fulfils all guaranteed parameters.The laboratory services are therefore an indispensable part of every Wehrhahn AAC project.The 'Development and Technology' DepartmentAt Wehrhahn, the laboratory is an integral part of the 'Development and Technology' department, which drives continuous innovation and product improvement. Innovations often originate from customer requirements and are implemented into new machines and production systems.The primary objectives of the department include:%u2022 Developing machines and technologies forfuture-proof autoclaved aerated concreteproducts that meet the demands of differentglobal markets.%u2022 Ensuring consistency in development by integrating innovations and Continuous Improvement Processes (CIP) into all projects immediatelyupon implementation.The Wehrhahn laboratory in conjunction with the %u2018Development and Technology%u2019 department are the cornerstones for the continuous further development of Wehrhahn systems and technologies. Customers all over the world rely on this. %u25cfSebastian Sanders, Product Manager AAC at Wehrhahn\ solutions are often required for changing and globally varying market requirements.
