GGBFS C Gr

Zero-carbon cement using ultra-fine GGBS (Ground Granulated Blast-furnace Slag)

Golden Fortune Ultrafine GGBS

The Global Standard for High-Performance, Low-Carbon Binders.

Golden Fortune Ultrafine GGBS is a premium-grade, micro-ground granulated blastfurnace slag (GGBS) engineered as a

high-performance supplementary cementitious material (SCM). Its exceptional fineness unlocks superior reactivity, making it a key component for producing advanced building materials that are stronger, more durable, and have a significantly lower carbon footprint.

Significantly improves concrete's reactivity, strength development (early and late stage), rheology for workability, and long-term durability against chemical attack.

Offers a carbon footprint over 95% lower than Ordinary Portland Cement (OPC), providing a direct and effective solution for producing low-carbon and zero-carbon concrete.

Its high whiteness and uniform particle size improve the finish of architectural concrete, enhance color vibrancy, and reduce the required dosage of pigments.

Engineered to match or exceed the performance of silica fume in demanding applications such as Ultra-High Performance Concrete (UHPC).

We have four production lines of GGBFS with annual capacity of 4.8 million MT, and eight production lines of cement with annual capacity of 10 million MT. The product grades of cement include P.O32.5/32.5R/42.5/42.5R/52.5/52.5R and ordinary Portland cement.

Our products have been sold in the Middle East, Singapore, South Korea, and Africa. Moreover, we have received a good reputation from our customers for high quality and good services.

Ground Granulated Blast Furnace Slag

Ground Granulated Blast furnace Slag (GGBFS) is made by quenching molten blast furnace slag (a by product of iron and steel making) in water to produce a glassy granular product that is then dried and ground into a fine powder GGBFS. It consists mainly of calcium and aluminum silicates and has a chemical composition similar to these respective natural minerals and to hydrated Portland cement. GGBFS is typically finer than Type 1 Portland cement. It is an off-white color powder with a specific gravity of about 2.88 and is handled and dispersed like Portland cement.
