13th International Symposium
on Concrete Roads BERLIN
Thursday, 21 June, 2018
Departure of the bus: 12:00
Meeting point: Hotel Lobby, TITANIC Chaussee
You will have the possibility to select a technical tour during your registration process.
The German limestone and cement industry has its origins in Rüdersdorf, where limestone has been quarried for over 700 years and where one of Germany’s earliest cement works was established in 1885. You can follow every step of the cement manufacturing process at the CEMEX Zement GmbH’s Rüdersdorf cement works, from extraction of the limestone using state-of-the-art technology in the limestone quarry, and the crushing, grinding and clinkerisation processes, to packaging and logistics. Extensive new building and reconstruction measures in the 1990s culminated in one of the most modern cement works in the world.
At peak times 5,300 tonnes of clinker are produced daily – seven days a week! Production takes place round the clock in several shifts. The process requires huge amounts of energy: the electricity consumption alone is equivalent to that of approx. 55,000 four-person households. 75% of this power is now generated from secondary fuels. This has made a significant contribution to reducing by 33% our plant’s direct CO2 emissions during production of our cement range, compared to 1990 emission levels. By using additional main ingredients such as limestone or granulated blast furnace slag, we produce cements of the strength classes 32.5 to 52.5 and in different mixtures. All these processes are controlled and monitored from a master control station.
CEMEX Zement GmbH in Rüdersdorf is a subsidiary of CEMEX Deutschland AG and is one of the largest cement producers in the Federal Republic of Germany. The parent company CEMEX has its headquarters in Mexico and is one of the largest cement producers in the world.
The excursion will also include the viewing of pilot projects using innovative concretes: a car park with pervious in-situ concrete for ecological drainage, a factory site road using a cement with several main ingredients, and a paved area using a quick setting concrete. We can also view approx. 50-year-old concrete surfaces subject to heavy goods vehicle traffic. The high point is the view from 108 metres elevation over the works and the surrounding area.
Sturdy shoes should be worn!
Be there live while building a bus stop in Berlin! On the excursion day, the precast elements are completely laid so that the stop can be used again at the end of the day.
What you can see:
- Inspection of precast elements before installation (coupling system, installation elements, equipment for height adjustment)
- Laying of precast elements directly from the truck
- Precise positioning
- Accurate height adjustment
- Pressing and joint filling with a special resin
The result is a high-quality and durable traffic surface in the shortest construction time.
Be there at the preparation of a concrete surface with low noise performance on one of the federal motorways nearby Berlin! This live demonstration will show you the latest grinding technology as well as machine and measurement technology. Here an old concrete road will be provided with a modern road surface. The objective is to reach the optimal performance in the following properties: skid resistance, evenness and low noise.
You will see:
- The latest grinding technology and powerful machine technology
- Modern road surface with low noise performance
- Measurement technology to determine the noise reduction, evenness and skid resistance
- Laser measurement technology to characterize the grinding texture and to acquire 3D-data of the road surface
Get yourself convinced of the machines and the performance of these new road surfaces. Besides, you can expect a snack bar with specialties from Berlin.
The General German Automobile Club (ADAC) operates one of the largest and most modern driving safety centres in Europe to the south of Berlin in Linthe, Brandenburg. The location also provides facilities for demonstrating the performance of concrete safety barriers.
Concrete is the ideal construction material for protective installations (concrete safety barriers) on roads due to its properties such as long service life, safety in use and economy. Concrete barriers show a very high level of protection from crossover accidents. Vehicles that leave the vehicle lane are contained and safely redirected back to the highway. Very different accident situations are demonstrated by a stunt driver approaching from a range of angles, showing how well concrete safety barriers stand up to different impacts. A rational method of unloading concrete barrier elements from the transport vehicle and installing them is also demonstrated.
We are grateful to the Hans Abel GmbH Co. KG Betonwerk Köthen for providing the Deltabloc precast concrete safety barrier system.
The oldest working boat lift in Germany is located at the eastern end of the Oder-Havel Canal near Niederfinow in Brandenburg. It was inaugurated in 1934 and can lift vessels over a vertical elevation of 36 metres. The boat lift is a listed industrial monument and an historic emblem of Germany’s engineering achievements.
The boat lift is a steel construction. Due to the increase in freight traffic on the canal it has now reached the limits of its capacity and no longer fulfils today’s requirements.
Construction of a new reinforced concrete boat lift began in 2007. The projected cost for the new lift is 285 million euros; it is designed to cater for the passage of 4.4 million freight tonnes per year and can accommodate ships up to 110 metres long and 11.4 metres wide. The new lift will remove a significant bottleneck on the only east-west trans-European waterway link between Szczecin, Poland and Duisburg, Germany.
