The Slabtester is now available with a flooding vessel to thaw the specimen immersed in water. The AKR - Alkali Silica Reactor is developed. The first instruments are delivered to the VDZ, Düsseldorf. We where sponsoring conferences in Regensburg, Gent, Siegen, Essen, München...

2008: Economical the best year ever. Many thanks to our customers! Ten people care about the development, the production administration and  sales. Nearly 50% of the goods are delivered in foreign countries. Redesign of the maturity simulator. The first CDF machine in the PR of China is installed. Schleibinger is sponsoring the ICAAR conference in  Trondheim Norway, the  SCC2008 conference  in Chicago, the Rheology conference in Regensburg and others. 

2009: The economical, or better said bank crisis was also hitting Schleibinger. But not so heavy as we feared before. Schleibinger was sponsoring the Nordic Rheology Conference and RILEM Conference on Rheology in Iceland. At the ibausil conference in Weimar the new developed Viskomat XL Rheometer was first shown.  In the Sichuan province of China the first BT2 and Viskomat NT have been installed, and Schleibinger was sponsoring the SCC2009 conference in Beijing.

2010: Schleibingers 20th birthday. Hip hip hooray! Thanks to all customers, suppliers, employees, friends, dealers who have been with us, this exciting 20 years! Its not time to take a rest, but i believe it is allowed to be a little bit proud...Read here and here the comment of the local newspapers (in German)

2011: When we moved to Buchbach in 1995 we have been a 3 people company, now we are 9 people. The turnover increased  to more the 1 Mio. EUR. So we expanded our building from 200 to more the 600 square meters.  The erection of the building started in summer, and was nearly finished until the end of the year.  And a big jubilee was the 20th Conference "Rheology of Building Materials" at the University of Applied Science in Regensburg. More then 100 people of more then 10 countries have been there. With this University we also established a research project sponsored by the German government.

2012: Our supplier for Ultrasonic test system for more then 15 years CNS-Farnell stopped its business in 2011. So we decided to develop our own system called vicasonic. Focus of the development was to measure the inner damage during the CDF freeze thaw test, as well as the early setting and hardening of mortar.
When the concrete rheometer BT2 came to market in 1998 controlling it with a Palm handheld computer via infrared was a revolutionary concept. Unfortunately also the Palm was canceled by its owner HP computers, USA. So we made a new design of the BT2 called eBT2. Its now electrical driven instead of the hand wheel, and controlled wireless via Bluetooth by an Android Smartphone. Lets hope that Googles Android will live at least as long the Palm operating system. In 2012 we also started cooperation with Aimil for the Indian market. The first viskomat was delivered to Chile. In 2012 we could increase our turnover again.

2013: In cooperation with Putzmeister Germany (in between a Sany China branch) we started the development of a new teinstrument for testing the pumpability of fresh concrete. This new product is called SLIPER

2014: In the US standard ASTM C 1581 a test method for measuring the restrained shrinkage of concrete is defined. Schleibinger is now producing the first commercial available instrument, following these guideline. Its called Shrinkage-Ring. The first Viskomat was delivered to Sukhoi Log Cement in Russia.

2015: Schleibinger is increasing its production capacity with a computer controlled milling machine and a computer controlled turning center. We are now 25 years old and well established on the national ind international markets. We have got another patent for our shrinkage measurement bending plate.

2016: Schleibinger is now member of the RILEM Technical Comitee MRP: “Measuring Rheological Properties of Cement-based Materials”. RILEM Is the leading international organization for material research and testing. In February the conference “Rheology of Building Materials” was organized  at the OTH Regensburg.

2017: Schleibinger was invited to present its new developed concrete rheometer eBT-V at a conference in the BASF headquarter in Ludwigshafen, Germany and also at LafargeHolcim in Switzerland. Another new product was the Salt-Water-Freeze-Thaw (SWF) testing machine first installed at the Technical University Dortmund. We are the only producers of such device according to the EN 13687.

2018: Schleibinger is member of the Rilem comite 266-MRP "Measuring Rheological Properties of Cement-based Materials". So in May 2018 we participated at a big RILEM organized round robin test of concrete rheometers at the University d’Artois, IUT Bethune, France. You may see some pitctures in the RILEM report 2018 page 15. In cooperation with the BAM Berlin we have developed a new kind of ASR/AKR reactor with online monitoring of the expansion of the concrete probes over time. This new instrument, called AKROMAT, is coming to market in spring 2019. 

2019: Supported by the  Bayerischen Forschungsstiftung (Bavarian Research Fund) and in cooperation with the OTH Regensburg as well as four partner from precast and building material industry we are incoporated since 2015 in a project called : "SVBA – Selbstverdichtender Beton mit zeitnaher Aussteuerung der Mischungszusammensetzung im Betonmischer ~ SCC with online control of the mix properties in the concrete mixer". As a part of this project we deloped  three new SCC rheometer as an experimental platform. This devices have been installed at the OTH Regensburg and in two precast plants for testing and tuning. The experimental part of this project was finished in 2019. We participated in confrences and trade shows in München, Nürnberg, Leipzig, Ulm, Dresden, Weimar, Praha, Paris, Dubai and Nanjing.  Ower number of stuff members increased again and also our total turnover reached 1.8 Mio Euro. The export share was over 70% again. 

2020: This years started with several confernces as 2019. But the last day of the  29. Regensburg conference on March, 12th was also the start of the first Corona lockdown in Germany. So nearly all activieties, including a party for our 30th anniversary, have been cancelled in this remarkable and difficult year.  Nevertheless we could keep our tunover nearly in the same range as in 2019. Two patents, applied some years ago, have been granted in this year one for the AKROMAT and another for product coming in the near future. Let yourself be suprised! We started a research project with the RWTH Aachen and other partners focused on the secondary ettringite formation (SEF). In Germany each year more the 1 Million concrete sleepers are replaced. Maybe SEF is one reason for this damages. 

2021: Despite the still active Corona pandemic we could reach again the turnover of 2019. We installed first time a new developed freeze-thaw tester for thermal insulating products for building applications according to the EN 12091 standard. The first so called WF-machine was installed at the Forschungsinstitut für Wärmeschutz in Gräfelfing near Munich.  The 30. Rheology Conference in Regensburg was an online conference, but nevertheless a big success. 

2022: Even in 2022, the Corona pandemic still had a grip on private and business life. At the same time, Russia's attack on Ukraine began in the spring. The second WF system was delivered to Munich. The rheology conference in Regensburg was able to take place in person again. We decided to give the event a hybrid format. So lectures and participation in person but also online. Progress born out of Corona. The design of the salt-freeze system was revised because another order for this type was received from Poland. For the first time, Schleibinger took part in the world's largest trade fair, Bauma in Munich, with its own exhibition stand. We also particpated in the Big5 trade fair in Dubai.

2023: In March 2023, the mask requirement was lifted, the most visible sign of the Covid pandemic. But now the war in Ukraine meant that supply chains were still very strained. It was therefore not always easy to process the encouraging order intake on time. The SVBA project with the OTH Regensburg (see 2019) was concluded with the successful doctorate of our employee Dr. Ivan Parić, title: "Detection and in situ control of the rheological properties of SVB". The obsolescence of electronic components continued. We therefore had to develop partially new electronics for the Viskomat NT and Viskomat XL rheometers. Hardly visible to the customer but a technical challenge. Visible to the customer is the new high-tech housing of the electronics - developed and produced by Schleibinger.
In May, the SWF system, Generation II, was installed at Henkel Poland in Staporkow.
In 1964, the ibausil conference was fount at the GDR Building Academy and the University of Architecture and Civil Engineering in Weimar, an international forum for scientific discourse, which sees its aim, among other things, as bringing together science and construction practice in the geographical center of Europe. The conference takes place every 3 years. In 1994, Schleibinger took part in the first ibausil after the fall of the Berlin Wall. Delayed by Corona, the 21st ibausil took place in 2023 - Schleibinger was there again, as we has been for all the years. Although the snow disaster in southern Bavaria in early December 2023 almost prevented us from traveling, we still took part in the Big5 in Dubai. Shortly afterwards, we were invited by Prof. Plank, TU Munich, to give a lecture at a "China-German Symposium on Advanced Low Carbon Cementitious Materials for a Greener Environment” with more than 20 Chinese professors and researchers.
Schleibinger became even greener in 2023! A photovoltaic system with 164 solar modules, a 22 kWh battery unit and a maximum output of 67 kW peak makes Schleibinger almost autonomous from the power grid, at least from March to October.
