Additive for Super High-Strength Concrete
DENKA Σ80N is a special cement additive that allows for the manufacture of high-strength concrete (60~90N/mm²) even when using low cement amounts.
Suitable for precast products used in bridges and high-rise buildings
Improves abrasion-resistance to concrete (suitable in dam aprons)
Mitigates cracking caused by heat of hydration
Increases alkali-resistance (especially where cement volume is high and alkali content exceeds allowable limits)
