The research project should generate essential knowledge on the behaviour of different aggregates under accelerated conditions within ASR testing methods. The target was to obtain with different testing methods a consistent assessment of the alkali sensitivity of aggregates and concretes respectively and to clearly identify expansive reactions that are not caused by ASR.
In a CORNET (Collective Research Networking) research project, the project partners CRIC (Belgium), Smart minerals (Austria) and VDZ (Germany) had combined under the consortium leadership of the VDZ to determine characteristic variables for cement and mortar samples and correlate them with the results of concrete durability tests.
Goal of the research project was to generate a broad, scientific verified data base via corresponding leaching and shower tests (laboratory and outdoor tests) on carbon-concrete test specimen with different concrete covering of the carbon-fibres as well as with different percentages of the carbon-fibres to evaluate the environmental compatibility of the new, innovative composite building material “carbon-concrete”.
The aim of the C³ CarbonSpeed project was to create a guideline to complement the existing verification procedures of the building authorities (approval in individual cases, national technical approval) with a view to shortening the time required for the introduction of solutions with carbon concrete.
In the course of the project, VDZ planned, inter alia, to work together with the ibac, Aachen, to develop a data base for the environmental compatibility of the new composite construction carbon concrete, by leaching and irrigation trials.
As result a procedural instruction for an advanced intial testing should be formulated and the transferability onto conditions in practice should be assessed.
One of the aims was to compile ‘Guidelines for the use of crushed sands (fine RC aggregate) in the production of cement ̓ – referred to in the project as ‘R cement ̓.
The target of this research project was to develop a comprehensive database regarding the material parameters carbonation and chloride resistance for different cement types and concrete compositions. The investigations focused on concrete compositions that contain cements with low clinker/cement factors.
