Dhabdo - A protector for Indian Army at Siachen

Our army, who are serving our country at places such as Siachen, where the daily temperature goes below -5 degrees, Also, their camp consists of mostly tents made of cotton or canvas, which are not good protectors from the cold. So a type of concrete shall be developed that will not allow cold to enter their residence, and they won't have to turn their heater on for longer hours as the panels will not allow heat transfer from one side to another.
