Review of European standards and guidelines for grouts for pre-stressed structures

Within the research project “ Improvement of properties of grouts for prestressing tendons and/or ground anchors” in the European COST Materials Action 534 “ New Materials and Systems for Pre-stressed Concrete Structures” methods for testing rheology, stability of the grout suspension with respect to bleeding and settlement, setting time, expansion and mechanical strength of the grout were performed and evaluated. One of the aims of the project was to critically investigate which methods that are given in European standards and guidelines are indeed suited for testing grout in laboratory and on site. Some of the most interesting results and conclusions gathered during the project are presented in this paper.
