Wind turbines often work under very adverse environmental conditions due to their location, subjected to high levels of humidity, sea salt, gusts of wind, etc. The mortars used for the foundation joints must resist compressive fatigue under these conditions, making them a critical element of the wind turbine structure.
Insurance companies request the certification of these mortars by means of very special tests that we carry out in our laboratories.
The key point is to carry out the tests under the same environmental conditions that will be found on site. For this reason, a large number of tests are carried out inside a climatic chamber, tempering both the raw materials and the machinery, from the mixing to the final test.
Kneading is carried out under these conditions and then the drying time, air content, sedimentation and density are tested.
Two types of testing are carried out:
