Webb15 juni 2024 · The role of the porous structure can be taken on by open–cell solid foams, including open–cell metal foams. Due to the high pore density (usually above 90%) and completely open structure (large, empty cells connected to each other), there is sufficient space in which liquids can flow relatively freely. Webb5 apr. 2024 · Thermal properties of this concrete increase with a decrease in density. Density ranges from 300 kg/m 3 to 1600 kg/m 3 and it is an essential factor because it influences many other properties. It has high porosity, and low tensile strength compared to compressive strength and it is weak in withstanding the tensile loads.
