The development of offshore wind turbines in Germany and worldwide is becoming more efficient and cost effective. The substitution of a high-performance mortar grout typically used with a standardized OPC-grout could have significant economic advantages. The aim of the investigations presented was to compare typical cement grouts with an established high-performance mortar grout and, furthermore, to proof the usability of different OPC-grouts as a grout material in grouted joints for offshore wind turbines. A large-scale test facility for the simulation of filling processes for the in situ assembly of grouted joints was developed. In addition a submerged test facility was developed and was used for the investigations in order to quantify the hydration heat development under nearly realistic conditions. The investigations have shown considerable differences between the cement paste grouts applied and the high-performance mortar grout.
