Silica Fume Concrete is widely used in concrete and fiber cement industries. In addition to its pozzolanic properties its is also a very good filler due to its particle size. These combined properties lead to an extended life expectancy in corrosive environments (resistance to chlorides, acids and sulphates) and improved strength.
High performance concrete containing silica fume is one of the more important advanced materials necessary in the effort to rebuild our nation's infrastructure. Silica fume delivers increased toughness and resistance to abrasion and corrosion, improving sustainability and life-cycle cost efficiency.
Some examples of Silica fume concrete include use for highway bridges, parking decks, marine structures and bridge deck overlays and other applications that are typically subject to deterioration caused by corrosion, abrasion and chemical degradation. Silica fume improves concrete protection against deicing salts, seawater, traffic and heavy impact and other destructive environments.
Micro Silica fume Advantage for high performance concrete
When microsilica is added to ordinary Porland cement it enhances certain properties of concrete detailed below:
Bond improvement
lesser heat of hydration
reduction of alkali- aggregate reaction
more compressive strength
reduced permeability
Minimizes the bleeding
