Prestressing of concrete structures has many advantages such as higher capacity, less cross-sectional area and less cracks when compared with non-prestressed members of the same loading span. Prestressing is usually applied using a mechanical process where the reinforcement is stretched using hydraulic jacks, and then the concrete is casted. Once the concrete has gained an acceptable strength, the reinforcement is released. As a reaction, the reinforcement applies a compressive stress on the concrete, causing a prestress. However, utilizing the mechanical method to prestress textile CFRP reinforcement is very challenging, giving that each textile fiber will need its own jack, which is not feasible. Furthermore, these fibers are very sensitive to any transversal forces, which may result from the mechanical anchorage. An alternative to the mechanical prestressing method is the chemical prestressing method. In this method, an expansive agent is added to the cement which causes the concrete to expand, and thus stretching the reinforcement, which applies compressive stresses on the concrete as a reaction. Therefore, a joint research project was initiated to investigate the feasibility of implementing the chemical prestressing method in textile CFRP reinforced concrete, in particular thin concrete elements such as plates and shells. This paper aims to communicate the recent advances in this project as well as illustrating the methods and procedures used to measure the expansion of concrete and the strains within the reinforcement. It also shows the multidisciplinary nature of the project. Furthermore, it also gives a glim into the feature of the project.
