GGBS is used as a direct replacement for Portland cement, on a onetoone basis by weight. Replacement levels for GGBS vary from 30% to up to 85%. Typically 40 to 50% is used in most instances. The use of GGBS in addition to Portland cement in concrete in Europe is covered in the concrete standard EN 206:2013.
Yes GGBS is a good partial replacement for cement in concrete mix. It has many advantages: It is used as a hydraulic binder. It improves the quality and durability of concrete. It is cheaply available as a replacement material. It provides better workability. Sustainable benefits high resistance to attack by sulphate and other chemicals.
GGBS . mills ensures that VCEM GGBS has more stable chemical constituents as compared to other mineral additives, such as fly ash and silica fume. Proven Track Record: GGBS has been reliably in used for more than 100 years. In 1865, GGBS was firstly used in Germany. In France, GGBS was used in the construction of Paris Metro as early as 1889 ...

This paper strongly recommends use of at least 70% GGBS in all concrete, including superstructures. The initial slow strength gain with high percentage of GGBS can be overcome by the use of ultrafine slag (SCM) in small percentage (say around 3%). It is to be noted that cement manufacturers generally do not exceed 50% GGBS in slag cement.

To improve the durability of structures, usage of GGBS along with OPC in concrete is recommended in BS 6655:1986, ASTM CB89:1982, IS 456:2000 and GGBS to OPC in the range of 2570% shall be added to manufacture Portland Slag Cement as per IS . GGBS Advantages • Reduction in heat of hydration and minimization of Thermal cracks.
Slag Mill System We can provide a variety of mill systems suitable for granulated ground blastfurnace slag (GGBS) grinding, including open circuit and closed circuit systems with ball mill as the core equipment, vertical roller mill (VRM) systems, and final grinding system and semifinal grinding system with roller press as the core equipment.
Initially, various combinations of Cement Fly ash, Cement UFS were tested for its fresh hardened properties and later OPC 53 is partially replaced by GGBS at various percentages in concrete starting from 0,10,20,30,40,50,60 70 and based on the results GGBS is used up to 60% in M45 grade concrete for Pile Pile Cap works.

Dried and ground to a fine powder, GGBS can be used to make quality, sustainable concrete. To ensure its activation, GGBS is most often used with normal cement. It will typically replace 30 70% of cement on an equal weight basis. Reduction in CO 2 emissions The manufacture of normal cement (CEM I of EN 197) results in the emission of 930 kg of CO
The ground granulated blast furnace slag (GGBS) is usually added to cement as an admixture to produce blast furnace slag cement. The GGBS powder can significantly improve the comprehensive properties of concrete and cement products by replacing the amount of cement in them for various purposes. Blast furnace cement Advantages of Slag Cement
Portland Blastfurnace Cement (PBFC) is a homogeneous blend of Ordinary Portland cement (OPC) and Ground Granulated Blastfurnace Slag (GGBS/GGBFS), complying with SS EN 1971, BS 146 and SS 477, and suitable for use when moderate sulfate resistance or moderate heat of hydration is desired. Product. Typical GGBS Content. Specification. P197B.
A higher replacement of 132 pounds of cement with 17 pounds of Juno XP (RPL 35%), didn''t achieve the same strength as the reference mix but still met the strength specification and allowed for cost savings of more than 7 per cubic yard.
