Properties of Concrete Blocks | Hunker

Properties of Concrete Blocks | Hunker

Thermal conductivity tests performed by manufacturers determine the insulating properties. By reducing the concrete block density by volume and producing a lower-weight block, manufacturers increase the heat-insulating properties of the blocks. Solid grouting the cells of concrete blocks increases the insulating properties of a concrete block wall.

Thermal Conductivity of Brick - Civil Engineering

Thermal Conductivity of Brick - Civil Engineering

Thermal conductivity of a material is its ability to conduct heat. Good Bricks should have low thermal conductivity so that houses keep cool in summer and warm in winter. Special Insulating Bricks are sometimes required for thermal insulation in structures.. Common red bricks have a thermal conductivity of 0.6 Wm-1 K-1.For insulating bricks, the value is even lower 0.15 Wm-1 K-1.
