Lightweight clay aggregate that is expanded in a rotary kiln at 1200ºC.
Filling solution with good thermal behavior, suitable for application in geotechnical works, agriculture, and landscaping, namely drainage, landfills, planters, and green roofs.
APPLICATION RECOMMENDATIONS
It can be used loose, mixed with cement slurry, or as a lightweight aggregate in a specially formulated concrete. When executing screeds or concretes, mix with only 2/3 of the expected water, adding the remainder at the end to prevent excess water from causing flotation.
