High Performance Concrete (HPC) containing microsilica – has been identified as one of the more important advanced materials necessary in the effort 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 chemicals; 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.
