It is a typo, this is what I got from my connection in India:

Dear Nader,
Hello. I am delighted to see your mail. Regarding this MUD PHUSKA there
are certain physical properties that are described in the Indian
Standard. As per Hnadbook on Functional Requirements Of Buildings(Other
than Industrial Buildings),Bureau of Indian Standards-SP:41(S&T)-1987,
following are the properties of Mud Phuska,
Density = 1622 kg/cubic meter
Thermal Conductivity = 0.519 W/m.K
Spoecific Heat capacity = 0.88 kJ/kg.K
Kindly let me know if this helps.
