What is Aircrete with Styrofoam?

In one sense, aircrete is similar to insulated concrete forms (ICFs). It increases the insulation capacity of traditional concrete. Unlike ICFs, however, aircrete doesn't require separate polystyrene foam blocks or other rigid insulation that is subsequently connected with space in between for pouring a concrete wall.

How long will Aircrete last?

Fire-Resistant

A 100mm thick aircrete block can resist fire up to four hours.
