Igh Performance Concrete (HPC) containing microsilica – has been identified advanced materials to rebuild the nations infrastructure. In addition to increased strength and enhanced durability, HPC produced with microsilica delivers increased toughness; increased resistance to abrasion, corrosion and placement and life-cycle cost efficiencies.

Highway bridges, parking decks, marine structures and bridge deck overlays are subject to constant deterioration caused by rebar corrosion current, abrasion and chemical attack. Microsilica will protect concrete against deicing salts, seawater, road traffic and freeze/thaw cycles. Rebar corrosion activity and concrete deterioration are virtually eliminated, which minimizes maintenance expense. Key benefits include:

· Very low permeability to chloride and water intrusion.

· Extremely high electrical resistivity (20 to 100 times greater than ordinary concrete).

· Increased abrasion resistance on decks, floors, overlays and marine structures.

· Superior resistance to chemical attack from Chlorides, Acids, Nitrates and Sulfates.
