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.

Construction materials team and partners within the Karlsruhe Institute of Technology 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. Here you find an overview of BSG´s activities and a list of publications.

Variety and quality of analytical equipment plus colleague expertise inside Karlsruhe Institute of Technology 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.

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.

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.


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.
Foundation of Celitement GmbH
Celitement GmbH was founded 19th February 2009 in Karlsruhe.
