Development of High Performance Grouts for Post-Tensioned Tendons and Ground Anchors
The presented results are part of the COST 534 group project "Improvement of properties of grouts for prestressing tendons and/or ground anchors", which is dealing with the rheology of grouts and with the improvement of grout performance for prestressing tendons and ground anchors. Common procedures for testing the rheology, setting times, bleeding and volume change of grouts as well as new developed methods for testing grouts have been used in this project. Results of the influence of ingredients - cement and admixtures - on the parameters required in standards and guidelines are reported and the pros and cons of the reqiurements are discussed. Test methods and evaluation criteria are discussed and it will be shown that some of the prescribed test methods and requirements are not representative enough.
