It is created by using small lightweight Styro or EPS balls as an aggregate instead of the crushed stone that is used in regular concrete. It is not as strong as stonebased concrete mixes, but has other advantages such as increased thermal and sound insulation properties, easy shaping and formed by hand with sculpturing and construction tools.

Crushed stone is produced by crushing quarry rock, boulders, cobbles, or largesize gravel. Crushed aircooled blastfurnace slag is also used as fine or coarse aggregate. The aggregates are usually washed and graded at the pit or plant. Some variation in the type, quality, cleanliness, grading, moisture content, and other properties is expected.
