TESTING METHODS AND TECHNIQUES
Due to the complexity of the RRT+, the following six Group Priorities (GP1), managed by experienced and highly competent GP1 leaders, have been defined to adequately achieve the objectives of WG1:
The main objective of this GP1 is to provide a platform for mutual validation of advance, non-standardised experimental techniques developed in European laboratories. Some of the techniques that will be included are:
The main anticipated outcome is to evaluate efficiency and accuracy of considered advanced techniques to obtain certain parameters of concrete at early ages, as well as their repeatability and reproducibility.
The main objective of this GP1 is to provide a platform for comparison of different protocols used in different participating laboratories for evaluating microstructural properties of CBM. Following techniques are planned to be included:
The main anticipated outcome is better understanding of the hydration and microstructure development of CBM in particular when SCMs such as conventional materials (blast furnace slag, fly ash, limestone) and new materials (locally available by-products and residues according to a specific interest of each country) are incorporated in the binder system to create eco-concrete mixtures.
The aim of this work package is twofold: (1) to determine the transport properties that can be linked to a deterioration mechanism with emphasis to standard error and scope, and (2) to outline the boundary conditions, so that transport properties can be linked to models for predicting future behavior as identified in WP2.
In the present RRT they will be represented by following properties:
Most of these methods are standardized and performed routinely in most of the participating laboratories. Nevertheless, there is still potential for improving repeatability and reproducibility of these methods and initiatives for their customization, which is the main objective of GP1d.
Following techniques are planned to be included in the RRT:
The main benefit of RRT is to give a platform where all of the developed methods can be compared and validated under controlled conditions.
In the present RRT following tests will be included:
Fracture behavior of ordinary concrete and fiber reinforced concrete will be monitored, to highlight the applicability and benefits of standardized and non-standardised non-destructive methods.
