New production concept for precast slabs – improving competitiveness on residential market A new production concept – MultiSlab – developed by Abeo and Elematic, allows hollow-core producers to also use their existing casting beds for production of prestressed SL-decks. An SL-deck is a flexible and light precast slab targeted at the residential market. The slab can handle long spans and built-in value-adding solutions such as bathroom installations and floor heating pipes. The Finnish precast producer, Lujabetoni, is currently implementing the first MultiSlab production system for launch of the SL-Deck to the Finnish market at the start of 2018.
Flexible slab production Abeo, the company behind the innovative SL-deck, and Elematic, an international acting supplier of precast machinery and equipment, joined forces to develop a new production concept allowing precasters to cost-efficiently add SL-decks to their product range. The MultiSlab production concept utilizes existing casting beds. Steel plates are installed on top of those, e.g. two existing 1.2-meter casting beds can be covered with an app. 3.3meter wide steel plate. This enables production of either 2.4meter wide SL-decks or two lines of 1.2-meter wide hollowcore slabs.
When producing SL-decks, side forms are mounted on the casting bed with magnets. The magnet system means that the sides easily open/close for demoulding and can be removed when doing hollow-core production. All hollow-core machinery runs on a permanent outer rail and a removable rail on the middle of the casting bed, while a 3.3-meter wide SL-deck casting machine runs on the permanent outer rails.
A competitive edge “The precast industry is a competitive market with many producers looking for a competitive edge. The ‘MultiSlab’ concept is a cost-efficient way for producers to leverage investments in existing facilities and diversify their product portfolio,” says Lassi Järvinen, Technical Director of Elematic and continues: “Being able to produce multiple products on the same production line is not only a benefit in terms of being able to serve more market segments, but also makes it possible for producers to obtain a higher utilization of the production capacity and better cope with demand fluctuations between market segments.”
Existing casting beds can cheaply be converted to a ‘MultiSlab’-bed allowing production of either 2.4-meter SL-decks or two lines of 1.2-meter hollow-core slabs. 90
