... 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...

... movements, numerical simulations of mechanisms causing relative movement between the ungrouted steel members are carried out for different sea states, which are to be expected during grouting and hardening process. The effects of earlyage movement on the material properties of grout material are evaluated...

... sedimentation and segregation. It is possible that the aggregates in the grout sediment and segregate due to the movement of the connections. Another effect which can occur is structural damages in the cement paste matrix of the hardening grout material during the hydration process. On top of that, plastic...

In the experiments, in order to examine the dilution of grout material, stereometry and strength test of the grouted specimen, measurement of distributions of silica concentration and pH in the grouted...

... now. Thus, numerical method based on VOF method with the same condition, silicate grouting material was used for the calibration chamber test with injection pressure, 50kPa, 100kPa and 150kPa, is applied and analyzed in this study. INTRODUCTION The pressure grouting methods being currently carried...
