Benefits of Elkem Microsilica® for tunnel and mining projects
For tunnel and mining applications, Elkem Microsilica® is used in a variety of ways.
In sprayed concrete (shotcrete) mixtures, Elkem Microsilica® particles make the concrete mixture more cohesive, reducing rebound and wastage.
In many underground situations, microsilica's ability to increase concrete strength and reduce permeability is beneficial.
