Cemex develops special concrete mix for Polish project

Cemex, S.A.B. de C.V. has announced that Cemex in Poland participated in the construction of the Jordanki Cultural and Congress Centre, a multifunctional building located in the green ring of the Medieval Town of Torun, a UNESCO World Heritage Site. Cemex supplied over 30 000 cubic meters of concrete for this project, designed by the Spanish architect Fernando Menis.

To blend perfectly with the historic character of Torun’s gothic architecture, the Jordanki Centre was made of partially immersed raw brick and concrete. This mix of crushed brick and concrete—known as “Pikado”—was used to fill the 1 cm spaces between the bricks, providing an unusual visual effect. Based on the architect’s model, Cemex’s laboratory also developed a special architectural concrete containing aggregates that matched the specific texture and colour required by Menis for the façade, walls, polished floors, and sidewalk surfaces of the building.

As the new home of the Torun Symphony Orchestra, the Jordanki Center has a rehearsal room for which Cemex developed a concrete solution with special diffusers for the spread of sound. Cemex delivered a single-piece casting solution of walls - 10 m high, from 5 to 6 m wide, and 10 to 20 cm thick—with impressions of boards and diffusers.

“The Jordanki Cultural and Congress Centre is a prestigious project for us. We were the only ones to successfully pass the tests performed before the project’s implementation. During deliveries, we developed a lot of concrete mix applications that were both interesting and demanding. The most spectacular one was “Pikado,” which was a challenging but positive lesson for us,” said Slawomir Dobrowolski, Director of Mobile Concrete Plant Division for Cemex in Poland. “Collaboration with our customers is our priority. As exemplified by this project, we analyze the best possible solutions with our customer in the areas of technology or logistics that benefit both parties, so they produce additional projects for us to work on together in the future.”

Cemex’s cement and ready mix technology centres are part of the R&D collaboration network, headed by Cemex Research Group AG, based in Switzerland.
