Silica fume for cementing and high-performance systems
Ultra-fine amorphous silica supplied in densified and undensified forms. Used where a cementitious or refractory system needs a finer, more reactive mineral phase than cement alone provides.

Product overview
A pozzolanic addition that works at a particle scale the cement itself cannot reach.
Silica fume is an ultra-fine amorphous silica used to modify the microstructure of cementitious systems. In oil-well cementing it is specified where slurry stability, permeability and strength development need to be controlled together.
NPE supplies both densified and undensified forms. The choice affects batching, handling and dispersion, so it is agreed with the customer alongside the grade rather than assumed.
Grades and technical specifications are available on request. Each consignment is released against the specification agreed with the customer and shipped with the documentation the destination market requires.

Key benefits
What silica fume change in your system
Each point below is a reason the material is specified. Values are not published; grades and technical specifications are available on request.
Permeability control
Used where a denser, less permeable set matrix is required in the placed system.
Refractory duty
Used as a fine mineral addition in castables and monolithic refractory systems.
Form selection
Densified and undensified supply allows the form to match the customer's batching and dispersion practice.
Consistent supply
Supplied continuously against the agreed grade so mix designs stay stable.
Bulk or bagged
Packing formats selected for the destination market and handling equipment.
