Granules with reduced apparent density GSO
Descriptions and a table of characteristics of KERWOOD® foamed ceramic microspheres

A foamed ceramic microsphere of reduced bulk density. It was developed for lightweight dry mixtures as well as concrete and blocks. Lightweight granules are made with a maximum size of 0.1 — 5 mm. They are produced serially being a standard warehouse item.
