Highly or better insulative concrete

Should be just as strong and durable.
Should be around just as heavy.
Should offcourse be non hazardous.
-And non hazardous when it breaks or something. Inhaling dust from it when it happens should be just as bad not worse then breathing in dust from concrete.
Short: Should have the same characterics as concrete.

Maybe something could be added. Or maybe something could be replaced.

A house will warm up faster and stay warm longer.
-With an automatic system the heating will stop at the set temperature.
