Thermal properties of concrete walls.
The common ones are 400 grade and 500 grades.
Thermal mass is defined as.
As for the furring used for interior insulation the thermal resistance of the concrete masonry webs and any grouted cores should be accounted for when determining the thermal performance of the wall see tek 6 2c ref.
When using core insulation the insulation should occupy all.

Thermal mass properties the thickness of the material and the method of construction will change the r values of your walls and roof.
Its insulation value comes primarily from using it in thick slabs and hence isolating the insulated space from thermal fluxes in the environment.
It is an important asset for designers who need to cut heating and air conditioning costs associated with hvac systems and still keep building occupants comfortable.

The compressive strength of 500 grade is 2 3 0 mpa.
Concrete by itself has a very low r value a measure of thermal resistance.
The thermal properties of precast concrete help improve a building s energy performance.
And the thermal conductivity is 0 12 w m k the same with aerated concrete.
There are minimum r value requirements for these parts of your home specified under the building code of australia bca and dictated to by the state and climate zone in which you live.
