Finland-headquartered precast concrete production technology firm Elematic has launched its fully-automatic Modifier E9 concrete recycler and its concrete casting Extruder E9 machines – both of which are a first-of-its-kind in the Middle East – at The Big 5 exhibition.

The Big 5, which is the largest trade fair in the Middle East for building materials, as well as construction products and solutions, is being held on 25-28 November at the Dubai World Trade Center.

In an exclusive conversation with Construction Week, chief executive officer of Elematic, Mats Jungar, said: “The main benefit for clients is that for the same investment cost, you get 50% more production compared to the current machinery being deployed in the market. This in turn will increase the competitiveness of hollow core slabs on the market. You can now make more hollow cores, faster, at better quality, than what was previously possible.”

The fifth-generation Extruder E9 is up to 70% faster than machinery on the market, which is achieved by automation, optimised casting parameters, as well as a new design of extruding screws and independent screw drivers that speed up the process of producing hollow core slabs.

Commenting on the impact of the product in the construction sector, Jungar added: “Hollow core is the construction product that need the lowest amount of concrete and cement per square metre of construction. Because hollow core concrete is pre-stressed, you need lesser amounts of steel while constructing a building. For example, in a residential construction, you need only 3kg of steel while using hollow core concrete.”

“So, you cut the cost of steel by up to 85%, and in addition, you need very low amount of cement with the extrusion technology. With the new Extruder E9, we lower the use of cement by 10%, which is a considerable saving on cost.”

The products are also in line with the drive towards sustainability in the Middle East region, as it not only lowers cost and the amount of material used, but also boosts the recycling of concrete.

“We have launched the first system of its kind in the region to reuse concrete. The new fully-automatic Modifier E9 can mark and dig recesses and openings automatically when the concrete is unhardened. This dug up concrete can be fed directly into the Extruder E9, which not only mixes the recycled concrete with fresh concrete, but can also monitor the overall quality of the reused material.”

“This is currently the only solution on the market that permits you to reduce concrete waste, as well as further reduce the use of fresh cement. There is no other solution of this kind in the Middle East region.”

In addition, the Modifier E9 does not use any water in the digging process, which means that concrete removed from openings can be recycled back to the extruder in the hollow-core slab production process.

Furthermore, the Modifier E9 saves considerable time by eliminating the need for manual marking of cutting lines or making openings for lifting loop installations.

Commenting on the firm’s participation in The Big 5 2019, Elematic’s area sales director, Middle East, Curt Lindroth, said: “We have a long tradition at participating in The Big 5, and are very excited about presenting the latest generation of machines and systems to the region at the exhibition. The new Extruder E9 is ideal for new hollow-core slab manufacturers targeting big volumes and for existing factories to improve the production output.”
