99% Densified Silica Fume is a highly reactive pozzolan and gives concrete a denser Microstructure, Lower Permeability & Higher Electrical Resistivity leading to improved durability.
The durability of a reinforced concrete structure can be defined as the capability of the structure to maintain its original functional and structural characteristics during the expected service life in the exposure conditions it was intended for.

Combined with correct design and workmanship, Defines Silica Fume concrete offers characteristics that will ensure long term durability and service life.

• Defines Silica Fume is used to make the high strength concrete that is often essential in major projects, such as record breaking tall buildings, Roads and Bridge.
• These engineering applications requiring high strength concrete use microsilica as a cost effective means to increase compressive strength. Ultra-high strength concrete (UHSC), typically defined as >150MPa can be achieved using higher dosages of G-chem Defines Silica Fume Increased strength results from Micro silicas particle packing & pozzolanic reaction. In Micro Silica concrete, the thickness of the transition zone (interface) between the cementitious paste and aggregate is reduced and the CH crystals are smaller and more randomly oriented, resulting in decreased porosity & increased interface bonding strength.
