Cultural building made from choice aggregates

Cement manufacturer Cemex supplied over 30,000m3 of material for the construction of the Jordanki Cultural and Congress Centre in the UNESCO World Heritage Site of Torun in Poland.

As part of the company’s involvement, its laboratory developed a special architectural concrete containing aggregates that matched the specific texture and colour required by Spanish architect Fernando Menis for the façade, walls, polished floors, and sidewalk surfaces of the building.

A mixture of crushed brick and concrete, known as Pikado, was also used to fill in gaps between the brickwork to create a striking visual style designed to be in keeping with the medieval town’s gothic architecture.

Cemex also developed a concrete solution with special diffusers to be used in the Jordanki’s rehearsal room that will be the new home of the Torun Symphony Orchestra.

Single-piece wall castings, measuring 10m high, 5m to 6m wide and 10cm to 20cm thick, were made with impressions to spread the sound.

“The Jordanki Cultural and Congress Centre is a prestigious project for us,” Slawomir Dobrowolski, the director of mobile concrete plant at Cemex in Poland, said.

“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.”

Cemex is a building materials company that provides products and services in more than 50 countries.
