CONDENSIL, specialist in silica fume in France since 1987, work for the development and promotion of this by-product from the production of silicon metal.

Addition to multiple advantages, it is today mainly used in high and ultra-high-performance concretes, projected concretes, externally resistant concretes and low-carbon concretes.

By valuing silica fume, CONDENSIL defines itself as a actor involved in the ecological transition, the development of the circular economy and the support of the profession on the goals of carbon neutrality by 2050.

The benefits of silica fume in concretes:

• improving rheological characteristics,
• increased mechanical performance,
• gain on rebound,
• improving sustainability criteria,
• decrease in carbon footprint...
