Inland waterways are important for exporting goods from Eastern Finland. To develop new solutions for a sustainable and efficient transportation in these areas, INFUTURE project was launched that includes model-scale testing in Aalto Ice Tank. In order to define the ice conditions for the tests, a measurement campaign was launched that covered different areas of Saimaa and seasonal variation in 2021.
This paper presents the measurement results from the first measurement campaign on January. The measurements included flexural strength determination through cantilever beam and 3-point bending testing, strain modulus from the bending tests, ice density, and ice structure. The measured flexural strengths were 590 kPa and 780 kPa, on average, with cantilever beam and 3-point bending, respectively, giving a ratio of 1.3 between the methods. The measured strain modulus from cantilever beam and 3-point bending testing were 3.5 GPa and 3.4 GPa on average, respectively. The average density was 890 kg/m3. Both S1 and S2 ice were encountered, where the grain size varied from 0.2 cm to 5 cm when moved from the top surface towards the bottom of the ice.
