Ricardo Kocadag from the
Federal Institute for Materials Research invented it: the record made of concrete! In the BLN.FM studio he did a test run. The engineer grabbed the disc on a normal turntable. And we can say: Yes, definitely! We clearly recognized "(I Can't Get No) Satisfaction" from the Rolling Stones.
But why make a record of concrete? Ricardo Kocadag and his team want to prove that concrete can do more than you think. In any case, the "ultra-high performance concrete" that they have developed. The material consists not only of the usual mixture - cement, sand and water - but hardens by various admixtures and powder particularly robust and can be much finer work. Until now, concrete was no material for filigree imprints, fineness or even musicality. But for a turntable to play sounds, the embossing in the grooves must be so accurate that it can be picked up by the needle of the turntable. At the same time the 6mm thin disc must be very stable. Ricardo Kocadag concrete record proves that it is possible.
Nevertheless, the future of the concrete remains its use in the construction of bridges, skyscrapers and roof structures. The new Super Concrete withstands five times the pressure, absorbs less water and is 30-50% lighter. He should not be introduced as a vinyl substitute, there are no plans. Whether the concrete slab sounds competitive? Hear it yourself when
