1. Product Description:

The Ground Granulated Blast Furnace Slag (GGBS) is a type of eco-friendly green building material and high quality secondary cementitious material for concrete and cement. It is recognized as one of the best secondary cementitious material for building high durable concrete strecture in the world by PhraseFinder"> today !GGBS has taken over by PhraseFinder"> top place of high-performance cement and concrete mineral additives with its unique characteristics of hydration,low-price raw material.

GGBS is obtained by quenching molten iron blastfurnace slag (a by- product of iron and steel making) in water or steam. It is then further grounded into the desired fineness in terms of the required particle size distributionm.

2. by PhraseFinder"> Applications & by PhraseFinder"> Benefits For the product:

Ⅰ. High-performance concrete additive, especially suitable for:

A. Preparation of the harbor and marine concrete structures with high resistance to corrosion by chloride ion.

B. Preparation of corrosion resistant concrete, improving durability of concrete structure in soleplate salt and alkali regions.

C. Preparation of concrete which provides by PhraseFinder"> effective prevention measures for the potential by PhraseFinder"> active alkali-aggregate reactions in concrete.

D. Preparation of low heat concrete which, effectively reducing the risk of temperature cracks in early period of the mass concrete structure.

E. Preparation of pumping concrete to effectively reduce the slump loss in the construction in summer, hence improving the workability of concrete.

F. Preparation of self compacting concrete to have effective control on bleeding and segregation of high fluidity concrete.

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

A. Production of medium content (30-50%) slag cement, improving the strength of all ages.

B. Production of low heat cement with high GGBS substitutions (50-70%), used for mass or port/marine concrete structures.
