About us

Celitement GmbH is a cooperation project between research and industry.

Celitements are high-quality hydraulic binders, which can be obtained via a patented process with good energy efficiency. Both raw material input and carbon dioxid emission are low. We investigate novel hydraulic binders while focussing on marketable products. We are able to use state of the art analytical equipement and rely on our long term expertise in construction materials.

Celitement GmbH was founded by the Schwenk Group, the Karlsruhe Institute of Technology (KIT) and by scientists of the KIT. A pilot plant has been engineered which started operating in 2011. The plant supplies sufficient quantities for testing of basic properties and recipes and also to get Celitements on the market.

Furthermore, process optimization was, until June 2013, the major topic of a research project funded by the Federal Ministry of Education and Research BMBF and Project Management Jülich ptj: "Celitement - developing a sustainable cement".
From October 2014 to September 2017 the project ran. It is also funded by the Federal Ministry of Education and Research BMBF and Project Management VDI.

2011 - Completion of the building and the pilot plant

The building is finished and the pilot plant with a production capacity of about 100 kg per day can start operations.

2009 - Foundation of Celitement GmbH

In order to develop both the binder and the process for commercial use Celitement GmbH was founded by Schwenk Group, Karlsruhe Institute of Technology KIT and scientists of KIT.

2007 - Class of binders protected by patents

The activities resulted in a series of patents for a new class of binders, the basis of Celitements. They ressemble OPC and are compatible to known binders. The big differences are the production route, energy efficient and low in emissions, and the somewhat surprising water content of the powderous binder.

1997 - Construction materials team within the KIT

The workgroup "Construction Materials" (BSG) within the Institute of Technical Chemistry - Department of Thermal Waste Treatment has published fairly relevant papers on calcium silicate hydrates. Variety and quality of analytical equipment plus colleague expertise inside KIT are crucial prerequistes of this work - the synchrotron facility ANgströmquelle KArlsruhe ANKA is one example.
A major impulse for the development of efficient and novel binders was gathered from the analysis of material flows and technology assessment of the Institute of Technology Assessment and Systems Analysis ITAS.

1994 - Investigation of calcium silicate hydrate structures

Hydraulic binders are research topics of Karlsruhe Institute of Technology for many years. Thereby, the focus was and still is on the structure and reaction of calcium silicate hydrates.
