Key Considerations

  • Calcitec® is used as the skeleton in a bituminous-filler mixture to create weight for the blend.
  • It is compatible with neat and oxidized bitumen, as well as SBS-modified bitumen.
  • Calcitec® is used in mixtures for flooring solutions to create weight and stability.
  • Thanks to the consistency in whiteness, absorption and fineness, it contributes to a more efficient performance in your process.
  • Calcitec® can partially replace cement in the mix, once certified according to the Equivalent Concrete Performance Concept in line with European Concrete Standard EN 206.

Product Variations

bitumonous_roofing_carpet

Calcitec® for bituminous roofing & shingles

Calcitec® in the mix results in high-performance membranes and shingles for long-lasting roofing applications.

office_carpet

Calcitec® for carpet backing & luxury vinyl flooring

Calcitec® is used where carpet backing flooring needs to achieve the correct weight per square meter, and luxury vinyl flooring needs performant stability layers. 

clay_bricks_wall

Calcitec® for clay bricks

Calcitec® is used for facade clay brick production, as clay has compounds of silica, alumina, feldspar, and iron oxides. It changes the brick’s color to yellow or cream. With coloring agents, this can be corrected to produce a broad color portfolio of trendy bricks. So, it will burn to a brown, pink, or red brick, depending on the amount of iron oxide in the clay.

concrete

Calcitec® for concrete

Calcitec® is engineered milled limestones for all types of ready-mix and precast concrete. Better pumpability is achieved thanks to the presence of numerous microfines below 2µm, which helps to increase the archaeological behavior of the mixes. These microfines also result in a product with consistent behavior in water absorption, which is highly valued for self-compacting concrete.
