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

Tangshan Tongshun Industry And Trading Co., Ltd. supplies ground granulated blast furnace slag (GGBFS) that complies with BS 669, the British standard for slag cementitious materials. The product is presented as an industrial‑grade powder designed to act as a supplementary cementitious material in concrete mixes. While the listing does not provide a numerical fineness, the material is described as having a high granulation level that improves workability and reduces permeability. Packaging options include bulk or bagged forms suitable for large‑scale construction projects.

In the broader market, GGBFS typically exhibits a fineness of around 6000 cm²/g and a specific gravity of about 2.9, both of which are recognised as standard values for this class of slag. Moisture content is usually kept below 0.5 % to prevent agglomeration, and the material is often stored in dry, sealed conditions at temperatures between 5 °C and 30 °C. When used at 30‑70 % replacement of ordinary Portland cement, the slag can increase 28‑day compressive strength by up to 10 % and enhance resistance to chemical attack, which aligns with the performance benefits highlighted in the description.

The slag is widely used by concrete producers, precast manufacturers and infrastructure contractors seeking durable, low‑carbon concrete solutions. Buyers should confirm the minimum order quantity, accepted Incoterms and payment method directly with the supplier, as these details are not disclosed in the listing. Freight is normally arranged from the supplier’s Tangshan facility in Hebei province, and terms such as FOB Tangshan or CIF Shanghai can be negotiated. It is advisable to request a material test report confirming compliance with BS 669 before finalising any purchase.
