Blast Furnace Slag
We are leading distributors and exporters of granulated blast furnace slag and ground granulated blast furnace slag, with sourcing from the largest steel producers in India.
Range of Blast Furnace Slag Products
Granulated Blast Furnace Slag (GBFS)
By-product from the manufacturing of steel in a blast furnace. Initially in its molten form, it is diverted to a granulator where it is quenched with water and rapidly cooled to form glassy, non-metallic granules which are silicates and aluminosilicates of calcium. These granules are dried to produce Granulated Blast Furnace Slag (GBFS)
Ground Granulated Blast Furnace Slag (GGBFS)
GBFS is ground to a controlled fineness through vertical roller mills or ball mills with the latest technology and quality control systems to produce Ground Granulated Blast Furnace Slag (GGBFS). The grinding process takes account of mean particle size, grading (particle size distribution) and particle shape, thus giving quality-assured material in off-white colour which is consistent, predictable and suitable for varied applications

Applications
GBFS is mainly used for grinding and producing GGBFS as well as blended cements with slag. GBFS is also used as an effective replacement of natural sand / crushed sand in concrete as a fine aggregate.
GGBFS enhances long-term performance and durability characteristics in concrete while reducing life-cycle and maintenance costs. General replacement of cement with GGBFS in concrete can be 20-80% by weight.

FAQ’s
The large generation of blast furnace slag in India has given birth to plenty of unorganized traders and exporters, who have no product knowledge nor any understanding of the business. Such fly-by-night operators often rely on malpractices to misguide customers and sell substandard quality products at cheap, below-market prices to make a quick buck.
Beware, a lower price always comes with compromises and risks. An apparent short-term gain could get wiped out by much bigger losses and long-term damage to the reputation and business of the buyer - with disastrous effects on concrete and significant construction hazards perhaps leading to death of people in case the concrete structure collapses!
Please check the following before procuring coal combustion products from any supplier:
Authenticity
- Authorised distributorship/ sales promoter agreement with the steel producer
- Verifiable sales volumes in past 12 months and customer testimonials
- Financial standing and resources of the company (due diligence reports can be bought online)
Organization
- Team size and structure
- Bios of management, technical and operations personnel
- Sustainability focus and business continuity planning
Quality Control
- Quality control process
- Historical quality data, third party test reports
- Detailed bag specifications to see GSM of fabric, weight of bag, liner, lamination, etc.
Operations
- Supply chain capabilities
- Assured load rate in case of bulk or break bulk exports, along with risk management process
The discharge of big bags into bulk tankers or batching plants is very often problematic, due to lumps created by fine particles due to vibration, ambient humidity, temperature fluctuations and compaction during shipping, transportation and storage.
JAYCEE recommends a simple but effective de-bagging facility to remove lumps, and load bulk tankers/ silos in a dust-free manner. The debagging equipment is furnished with an in-built lump breaker macerating any material containing lumps again into free flowing powder. Two operators are required to man the system and one forklift or Hydra is required to carry the big bags to the lift-up point of the de-bagging station. All large customers and distributors in every territory should install a de-bagging station with in-built lump breaker to have seamless discharge of big bags. JAYCEE can also provide such systems in cases where it is not available locally.
