Is vermiculite suitable for lightweight concrete?

Yes, GRANUTEC® vermiculite is highly suitable for lightweight, insulating, and fire-resistant concrete. Mixed with Portland cement and water, it forms a lighter and more thermally efficient concrete without compromising mechanical strength.

This concrete is used for roofing, slabs, screeds, or precast elements. It combines ease of handling, fire resistance and low thermal conductivity.

Formulations can be adjusted with or without resin depending on the project’s needs. Vermiculite acts as a technical aggregate that stabilizes the mix while reducing the weight of the finished product.
