Import Ground Granulated Blast Furnace Slag — Buy in Bulk from Supplier in India

Ground granulated blast furnace slag (GGBFS) is a fine, glassy powder produced by rapidly cooling molten iron slag from a blast furnace. This material, supplied by Quality Polytech from Karnataka, India, is used as a partial replacement for Portland cement in concrete mixes. The product’s fineness is measured at 370 m2/kg, a critical factor for its reactivity and performance in concrete applications, while its nil Le-Chatelier expansion confirms soundness and structural stability.

The slag’s chemical composition typically includes calcium oxide, silicon dioxide, and aluminum oxide, which contribute to its cementitious properties. GGBFS is known for its low permeability, which enhances durability in aggressive environments like marine or chemical exposure. Standard industry practice often targets a glass content of 85-95% for optimal performance, though Quality Polytech’s listing specifies no additional compositional details. Its use reduces the carbon footprint of concrete by lowering clinker demand in cement production.

Infrastructure projects such as highways, bridges, and high-rise buildings commonly use GGBFS to improve strength and longevity. Contractors and concrete producers source this material for bulk supply, often seeking consistent particle size distribution and moisture content below 1%. Packaging and logistics details are not specified by the supplier, so buyers should confirm bulk handling options, lead times, and port of loading in Mangalore for efficient import.

Quality Polytech is based in Baikampady Industrial Area, Mangalore, Karnataka, India, and operates as an imported-tier supplier on the platform. The company’s profile indicates a harbor trust tier, though its response rate and average response time are currently recorded as zero, suggesting buyers may need to follow up directly for timely inquiries. No additional verification signals or certifications are listed for this supplier.

The supplier’s description focuses on the industrial-grade nature of its GGBFS, emphasizing eco-friendly properties and concrete performance enhancements. However, the profile does not specify years in operation, production capacity, or client references. Buyers should confirm the supplier’s ability to meet bulk orders and verify whether certifications such as ISO or SGS are held, as these are mentioned in the product write-up but not explicitly attributed to Quality Polytech.
