Because cinder blocks are made with different fillers, their thermal conductivity can have other indicators. If the filler is coquina or sawdust, the coefficient in this case will be equal to 0.27 W/m*K, and the filler of coarse crushed stone will have a high index of strength, but the maximum thermal conductivity. Depending on the composition of the filler changes and density of cinder blocks.
On average, this physical value ranges from 750 to 1455 kg / m. cube. Accordingly, changes and the strength of cinder blocks, and their thermal conductivity.
Compressive strength is measured by placing the product on a press and pressing the top plate. If the complete destruction of the sample occurs at a pressure of 50 kilograms, then the mark will be assigned to the product correspondingly. Marks of cinder blocks range from M-35 to M-150.
