SL-decks have been specifically developed to cope with the higher complexity and stricter building codes of residential building projects.
The key that makes this possible is the Light Aggregate Casting (LAC) machine, which has been developed and patented by Abeo for production of the light-aggregate concrete blocks making up the bottom half of the SL-Deck..
Unique production technology: Low weight, where needed
With the SL-deck casting machine, it is possible to leave out specific blocks and place the light-weight blocks exactly where needed in the slab. This provides a high level of flexibility in a low-weight and low cost slab.
In the areas where blocks are omitted, it is possible to make various cast-in solutions (e.g. drains, installations, sprinklers, electricity etc.) and thus solve some of the main challenges arising when precast slabs are used in residential projects.
About the LAC machine
The SL-deck production machine can be built for production of up to 3.6-meter wide SL-decks of any length. The LAC machine enables manufacturers of the SL-Deck to cast a 100 m bed of lightweight concrete in app. 30 minutes, completing up to 3 m per minute. Casting is done fully automatic based on an input file generated by the production planning software provided by Abeo.
Maintenance and cleaning is made easy by full access to all moving parts. Another benefit of the LAC machine is the very low operating costs and high level of reliability. Due to the simple and robust design of the machine, costly shutdowns and repairs are rare despite producing hundreds of thousands of blocks every year.
The SL-deck casting machine has been developed and patented by Abeo and makes it possible to decide exactly which areas of the slab should be low-weight and where flexibility is needed for cast-in solutions and other things.
The LAC machine has a touchscreen control panel allowing the operator to monitor production status and read built-in machine sensors.
