The results showed that the materials based on CEM II seemed to be more sensible to a creation of mesoporosity after carbonation than the CEM I based materials.
Effectively, using nitrogen adsorption on different materials, while a decrease in the micropores (r< 2 nm) was observed, the results in this study indicate that the creation of mesoporosity (r> 2 nm) is more significant in CEM II materials than CEM I materials.

When acoustic wave is incident on the underwater sound isolation materials, the materials produce dynamic stress or strain to transfer generating energy into heat energy.
So the materials play a role of vibration suppression and reducing radiation noise.
