Thermal properties of foam concrete can be improved


Thermal properties of foam concrete can be improved by several types of additives, i.e., coir fiber, which applied resulted in higher heat capacity and lower thermal conductivity of the FC, as well as polypropylene fibers, which allowed for the reduction in the thermal conductivity and improved the mechanical properties of foam concrete. Moreover, the degree of thermal insulation in FC might be influenced by the mixture composition, such as aggregate type and mineral admixtures. Next, conductivity associated with FC based on a synthetic foaming agent was less sensitive to changes in air content than concrete produced using a protein-based foaming agent. The thermal conductivity of FC depends on density, moisture content, and components used in the material. The number of pores and their distribution have a crucial effect on thermal insulation. Foam concrete’s thermal conductivity values constitute 5–30% of the obtained for normal concrete and range from 0.1 to 0.7 Wm−1K−1 for dry density values of 600–1600 kg/m3, reducing with decreasing densities. These findings are consistent with the results obtained, where the thermal conductivity of foam concrete ranged from 0.389 to 0.734 Wm−1K−1 at a density of 1200, 1400, and 1600 kg/m3. For the foam concrete of a density from 860 kg/m3 to 1245 kg/m3, the thermal conductivity varied from 0.021 to 0.035 Wm−1K−1.
