Advantages
Increase Concrete Strength: Silcrete micro-silica used in concrete improves mechanical properties including compressive strength and modulus of elasticity. High ultimate compressive strengths (8,000-20,000 psi), proportionate to amount of Silcrete micro-silica and the water-to-cementations ratio. High strength Silcrete concrete can be used for high-rise structures and substructures of high performance concrete bridges for pre-cast, pre-stressed girders.
Durability: Silcrete micro-silica enhances concrete durability by significantly improving resistance to chemicals and abrasion
Corrosion Protection: Reduced permeability provides better protection for steel against chloride ion attack and resistance to corrosion especially in marine structures.
Constructability: Silcrete micro-silica used in conjunction with Portland cement and fly ash enhances early strength, reduces temperature increase caused by hydration. High early strengths, assures increased efficiency and greater cost effectiveness in production of pre-stressed and pre-cast concrete.
Pre-Cast Concrete: In pre-cast concrete (made in a manufacturing environment) it is more efficient, and results in cost and time savings.
- High early and higher ultimate compressive strengths.
- Eliminates steam curing.
- Savings on heating costs and rapid turnover of forms.
