The silicate Rotec® lightweight aggregates
The raw material for the innovative ROTEC® lightweight aggregates was formed around 12,900 years ago during the last volcanic eruption in Germany. Air-entrained natural pumice - a pure, silicate mineral with unique properties - formed directly beneath the earth's surface.
ROTOCELL® and ROTOCELL PLUS® - high-performance, mineral lightweight aggregates with outstanding insulating and processing properties - are produced from this high-quality raw material. The range is complemented by ROTOBASE®, a siliceous rock flour that sustainably improves the strength and durability of plasters, mortars and concretes through chemical reaction with cement.
ROTOCELL®
THE LIGHT, HIGH-PURITY MINERAL GRANULATE
ROTOCELL® is a light, dry granulate that is refined into high-purity grains using special processes.
ROTOCELL PLUS®
THE HYDROPHOBIC HIGH-TECH AGGREGATE
The mineral lightweight aggregate ROTOCELL® is refined into the water-repellent high-tech granulate ROTOCELL PLUS® using a patented process.
ROTOBASE®
THE SILICEOUS STONE POWDER
ROTOBASE® is an innovative additive for cement- and lime-based building materials. It improves the properties of plasters, mortars, concretes, tile adhesives and other construction chemistry products as well as polishing and grinding agents.
