Hasopor foam glass is a lightweight cellular glass aggregate, 10-60 mm, mainly made from recycled glass containers, collected from households in Sweden. After going through the nearby glass sorting facility, the glass is dried and milled to a very fine glass powder. The powder is mixed with an activator and the powder is heated in a kiln at approximately 1000 degrees Celcius and expands 4-5 times. The output from the kiln sets and breaks by cooling, into a granular material of 10-60 mm with a dry bulk density of approximately 180 kg/m3.
Hasopor foam glass is mainly used as a lightweight filling material, by customers who wish to get environmental and sustainable benefits. The most common use cases are groundwork for road, house and geotechnical construction areas.
