54 PRODUCTION TECHNOLOGY AAC WORLDWIDE %u2022 2.2025Step 3: The holding frame is placed on a mould with fresh cast AAC product and the entire reinforcement is inserted into the fresh cake. The holding frame for the reinforcement remains on the mould, which is transported to the rising area.Step 4: After the rising, the reinforcement manipulator lifts the holding frame before the subsequent cutting process. The reinforcement remains in the green cake. To pull out the reinforcement frame with the needles, the needles must first be disconnected/unlocked from the reinforcement.Step 5: Later, the green cake with the invisiblereinforcement is treated like a cake for blocks. However, in the cutting line, it is necessary to ensure that the cutting wires are correctly positioned to cut only into the green aerated concrete material and not into the steel.Keeping an eye on the inside: Product trackingEspecially for load-bearing wall panels and AAC floor and ceiling panels, the architect must determine, in consultation with a structural engineer, what type of reinforcement is required for each individual panel. This depends mainly on the position in the building where the panels are used and what loads need to be taken into account there.Therefore, at the end of the production process, namely when the panels are being packed or prepared for transport, it must be clear for which project, building, floor and position the respective panel is to be used.This allocation/identification and tracking can be done manually on paper for small capacity plants.However, for larger capacity plants in particular, an extension of the standard control systems with a data tracking system is recommended. This system can track every cake across the entire production line and, for panels, even every single element.Concepts for existing and new plantsAn AAC manufacturer can either start from the beginning with a portfolio of reinforced elements or expand production later. For this, the expansion must be considered in the basic planning of the plant. Below, the two different concepts are described. Both solutions have been successfully realised by Masa GmbH as well as Hess AAC Systems B.V. %u2013 now part of the Masa WhiteHub umbrella brand %u2013 in projects for international customers.Step 1: The reinforcement is protected against corrosion by immersion in a coating bath. Step 3: The entire reinforcement is inserted into the fresh cake.
