The considered range of foam concrete densities

The analysis of the thermal conductivity dependency on the density detects the linear fit as a best-fitting curve for the considered range of FC densities. The coefficients of the linear fit are depicted. Exceptionally high values of the coefficient of determination, R2, were achieved in the field of 0.96–0.99. Hence, the linear interpolation was confirmed as a realistic description of the thermal conductivity and density relation in the range of the tested FC densities. Of course, the comments and limitations of the approximation curves mentioned regarding compressive strength are also valid. The presented study is focused on the decisive properties of ultra-light foam concrete for thermal insulation applications in civil engineering. A relatively large range of tested densities made it possible to investigate the influence of the type of foaming agent and the type of binder on the characteristics of foam concrete. Therefore, the presented results add more insight into the combined effect of the mentioned various components of FC on structure, compressive strength, and thermal conductivity. The results confirmed the well-known dependency: the firmly intended lower density is associated with the lower compressive strength of FC, but at the same time, the desired lower conductivity relates to lower density. Hence, a balance between these distinguishing features should be sought to minimize thermal conductivity and maximize strength as much as possible.
