FOUNDING HISTORY of CO33

Stability was a particular challenge. The reinforcement was to be used to support the bending tension, which would retain its shape when the bench was loaded. However, with a concrete thickness of only 3 cm chosen for my bench, this was a problem. The concrete cover to the iron would be far too small, so stainless steel reinforcement? - This would have worked, but as the moulds were to be filled on edge, the reinforcement could not be held in its intended position. The iron could have been anywhere, but not where it was supposed to be! Another idea was a recipe with fibres, which would have been the most obvious solution, but far from it. The fibres impair the flowability of the concrete enormously and would have been reluctant to cover the long filling distance. So all the work remained with the concrete after all. The material that can withstand a lot of pressure but forgives little bending.

So before my concrete bench project failed due to a lack of reinforcement, I developed a formula that would enable us to realise the bench in its final form and still create increasingly thin components that were resistant. The result was UHPC-ultra high performance concrete - without fibres. Once this hurdle had been overcome, all that remained was to cast the bench successfully, which we finally managed to do masterfully after a number of attempts. That was the birth of OPUS PRIMO - the FIRST WORK in Latin. From this mould, the OPUS collection was finally created in 2015 - a series of elegant furniture that can be easily transformed and combined.
