I'm modeling a thermal finite element model of RC frame ,so i have faced some problems although i could not solve them by any searching of a variety of articles

I'm looking for below cases :

1- A relation or formula between density and temperature of concrete?

2- A relation between conductivity and temperature of concrete?

3- A relation between specific heat and temperature?

4- ISO 834-1 code

Is there anyone to help?

Thank you

Best Regard.
