What is Ferrogel?
Ferrogel is an additive designed to enhance the quality, strength, reliability, and durability of concrete. Its key components include Microsilica powder, superplasticizer based on polycarboxylate ether, concrete fibers, and other additives for optimizing concrete performance based on the method of Microsilica gel production and the product class used. The Microsilica slurry product is a stable suspension of silica fume in water. Possessing pozzolanic properties, this product reacts with calcium hydroxide released during cement hydration. The resulting secondary products improve concrete sealing properties, impermeability, and mechanical and abrasion resistance.
Applications
Construction of water structures such as reservoirs, water storage facilities, canals, and water treatment plants.
Building concrete structures for docks, bridges, bridge decks, reservoirs, and dams.
Fabrication of beams, columns, and ceilings in diverse sizes and configurations.
Military and defense infrastructure projects.
Industrial floors subjected to dynamic and impact vibrations
Concrete surfaces, pavements, and roadways.
Construction of concrete structures in corrosive and acidic environments
Production of bulky concretes and concrete sections with high reinforcement density

Slurry
FS PR-642
Slurry (FS PR642)
This additive contains approximately 50 to 60% silica fume, which exceeds the silica fume content found in Microsilica gel. Generally, when enhancing concrete properties with silica fume addition, Microsilica slurry is a suitable choice.
Ferrogel
Base
FB SP110
Base FB SP110
Comprising roughly 50% Microsilica and polycarboxylate-based superplasticizer, this additive is employed in concrete requiring minimal slump retention. It is applied at the point of discharge and prior to pumping.
Ferrogel
Fiber Base
FFB SP110
Fiber Base FFB SP110
This additive contains about 50% Microsilica, superplasticizer based on polycarboxylate ether, and polypropylene fibers. It is used in concrete with minimal slump retention, serving at the point of discharge and prior to pumping. It is particularly effective in reducing shrinkage and surface cracks.
Ferrogel
High Slump
FSH R400
