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

The product offered is granulated blast furnace slag, a vitreous by‑product of iron‑making processes. It contains SiO2 33.42 %, CaO 40.15 %, MgO 8.35 %, Al2O3 14.69 %, Fe2O3 0.93 %, TiO2 0.63 % and SO3 0.10 % as confirmed by the supplier. These percentages give the material a latent hydraulic activity that can replace a portion of Portland cement. Tangshan Tongshun Industry And Trading Co., Ltd. supplies the slag in bulk for industrial use.

The granulated form provides a glassy amorphous structure that yields high resistance to alkali‑silica reaction and low water permeability. Typical bulk density for this slag is 2.5 g cm‑3 (standard range 2.4‑2.6 g cm‑3). Standard fineness measured by the Blaine method is about 3 200 cm² g‑1, which is typical for high‑performance concrete additives. The material is certified under ISO and SGS standards, confirming compliance with recognised quality systems.

In practice the slag is blended with ordinary Portland cement to improve compressive strength, durability and workability, especially in aggressive environments such as marine structures or high‑temperature foundations. Major users include concrete producers, road contractors and civil‑engineering firms that require sustainable cementitious solutions. The supplier states that trade can be arranged on CIF or T/T terms and that flexible minimum order quantities are available on request. Prospective buyers should confirm the exact MOQ, delivery schedule and payment conditions directly with the supplier.
