When the thermal mass of the concrete is heated the warm slab acts as a radiator distributing even heat throughout the structure.

Thermal conductivity of concrete floor slab.

It is a readymixed concrete solution offering improved thermal conductivity performance actual range λ 0 45 to 0 54 w m k with assured structural performance 30 n mm2. A reasonable r value for a normal concrete slab can be estimated using an r value the thermal resistance per inch of thickness between 0 1 and 0 2 and multiplying it times the slab thickness. Thermal conductivity of building materials thermal conductivity of building materials acoustic plasterboard aerated concrete slab 500kg m3 aluminium asphalt 1700kg m3 bitumen impregnated fibreboard brickwork outer leaf 1700kg m3 brickwork inner leaf 1700kg m3 dense aggregate concrete block 1800 kg m3 exposed. The thermal performance of standard o reilly hol lowcore floor slabs is 25 better in average com paring to the same slabs with open voids.

Low conductivity and structural concrete low thermally conductive concrete is proven to improve energy performance in buildings. A sensitivity analysis is performed to identify the governing parameters. Thermal conductivity of a concrete slab indicates the rate of heat transfer through the solid mass by conduction usually in regard to heat transfer to or from the ground. Thermal mass effect thermal mass is a property that enables precast concrete floors to absorb store and later release significant amounts of heat.

Initial test results have shown that. For a 6 inch slab r value would be between 0 6 and 1 2. The coefficient of thermal conductivity k is proportional to density of the concrete among other factors. The thermal performance of standard o reilly hollowcore floor slabs is 25 better in average com paring to the same slabs with open voids.

A nonlinear optimization method is applied to improve the thermal conductivity. The thermal resistance or r value m 2 k w is calculated by dividing the thickness of the material in metres by the k value. Generally speaking lower density concrete provides better insulation than higher density concrete. Thermal conductivity is a material property that describes ability to conduct heat thermal conductivity can be defined as the quantity of heat transmitted through a unit thickness of a material in a direction normal to a surface of unit area due to a unit temperature gradient under steady state conditions.

The thermal analysis of concrete members according to en 1992 1 2 shows errors. Improvements of the involved physical parameters are indicated. The picture above shows a concrete floor we re about to pour with radiant heating tubes installed.
