Concrete additives

Condensil develops a wide range of mineral additions for all needs. And in addition to supplying specialized materials, Condensil will help you find the optimum mix design for your special concretes:
· Civil works (viaducts, bridges, underpasses, etc.): HPC and VHPC, concrete subject to freeze/thaw cycles, concretes subject to sulfate attack or alkali-aggregate reaction (footings, raft foundations, massive structures, etc.),
· Ultra-high-performance fiber-reinforced concrete (UHPFRC) for a wide range of applications, e.g. bridge decks, footbridges, toll-station roofs, façade shading grids, street furniture, etc.
· Underground concrete: tunnels, deep foundations, diaphragm walls, etc.
· Dry and wet-process sprayed concrete (shotcrete
· Special works: nuclear power plants, tanks and agricultural works subject to chemical attack
· Special buildings: high-rise buildings using concrete subject to creep
· Drainage and sewage works, for impact and abrasion resistance

· Industrial floor slabs for good abrasion resistance

Condensil has developed a global service offering to help you in every way:
· Technical assistance in choosing silica fume, optimization of the concrete mix design and silica-fume content.
· Logistics support: transport, handling, storage.
· Different delivery formats: standard bags, bulk bags, bulk.

Through its involvement in the marketing of silica fume for enhancing concrete performance, Condensil has been part of the development of sustainable high-strength and high-performance concretes. Silica fume is a by-product of the production of silicon and ferrosilicon, which are made in an arc furnace through the reduction of quartz with carbonaceous materials at temperatures of 2000°C.
