Denka Fastrong

Early Strengthening Additive for Concrete.

Denka Fastrong is an early strengthening
additive for precast
concrete that promotes the formation of
ettringite and hydration of Portland
cement to enhance early strength. This
cement additive is particularly effective
in improving the strength of concrete
products that use by-products such as
blast furnace slag(GGBS), fly ash, etc.

Key Benefits

• Improves early strength when blast furnace slag
  and other by-products are used, and suppresses
  strength loss during demolding
• The early-strength enhancement effect can suppress
  steam curing temperatures during production,
  contributing to a reduction in environmental impact

Typical Applications:

• Precast elements e.g. segments, box culverts
• Increased early strength development in concrete, including concrete with SCM’s
