High-performance concrete GGBS - BS EN

1, High-performance concrete additive, especially suitable for:

• Preparation of the harbor and marine concrete structures with high
  resistance to corrosion by chloride ion.
• Preparation of corrosion-resistant concrete, improving durability of
  concrete structure in soleplate salt and alkali regions.
• Preparation of concrete which provides effective prevention measures for the
  potential active alkali-aggregate reactions in concrete.
• Preparation of low heat concrete which, effectively reducing the risk of
  temperature cracks in early period of the mass concrete structure.
• Preparation of pumping concrete to effectively reduce the slump loss in the
  construction in summer, hence improving the workability of concrete.
• Preparation of self-compacting concrete to have effective control on
  bleeding and segregation of high fluidity concrete.

2, Super-reactive cementitious additives, especially suitable
for:

· Production of medium content (30-50%) slag cement, improving
the strength of all ages.
· Production of low heat cement with high
· GGBS substitutions (50-70%), used for mass or port/marine concrete
structures.
