Shrinkage Cracking of Self Compacting Concrete (SCC) with GGBS
The use of Ground Granulated Blast Furnace Slag (GGBS) in Self Compacting Concrete (SCC) has become an alternative choice to improve the fresh properties and to reduce the amount of cement. Such use of GGBS has also been recognized as a mean toward a more sustainable and green construction....
Strenght Of Concrete By Use Of Ggbs
Another major hurdle of extensive use of GGBS concrete lies in the little source of supply of GGBS. As Hong Kong is not a major producer of steel, GGBS as a byproduct of steel has to be imported overseas and this introduces higher material cost due to transportation and the supply of GGBS is unstable and unsteady. ...

Use of Water Reducers, Retarders, and Superplasticizer
The use of WRA is defined as Type A in ASTM C 494. WRA affects mainly the fresh properties of concrete by reducing the amount of water used by 5% to 12% while maintaining a certain level of consistency, measured by the slump as prescribed in ASTM C 14390. The use of WRA may accelerate or retard the initial setting time of concrete....

All About GGBS: Frequently Asked Questions (FAQs) about ...
02. How is GGBS produced? What are its applications? GGBS is obtained by quenching molten iron blast furnace slag immediately in water or stream, to produce a glassy granular product that is then dried and ground into a fine powder. It is an excellent binder to produce high performance cement and concrete....
GR Enterprises, GGBS
GGBS is a fine powder, used in concrete as "cement", major use in ready mixed concrete (RMC) or in the production of Portland slag cement. GGBS replaces a substantial proportion of normal cement (Ordinary Portland Cement) in RMC. The mixing varies from 30% to 70% approximately (generally 50%)....
