Application:

Granulated Blast Furnace Slag has a glassy structure and can be used as a fine aggregate or binder. GBFS is commonly used in the manufacture of blended cements and the ready-mix concrete plant where it is inter-ground or blended separately with cement usually at a 20% – 40% proportion. Unblended GBFS is can be used in road pavements and building products.

Packing

Packing can be arranged based on:
1. Bulk in vessels (GBFS)
2. In 50kg bags in 1-2MT Sling Bags or Buyers option
3. In Bulk (Big Bags) of 1-2MT Sling Bags

All shipment compartments will be sealed and waterproofed on board vessels.

Description

Blast-furnace slag, a by-product of iron and steel industry, is mixed with cement for use as a cement alternative additives. It is an eco-friendly product, which enables reduced energy use and CO2 emissions in its production process by around 40% as compared to producing concrete from cement only, in addition to saving natural resources such as cement raw materials and limestone. Iron and steel manufacturers produce high-quality iron and steel with blast furnaces and a certain volume of blast-furnace slag as by product is generated in the process. BFS is used to make durable concrete structures in combination with ordinary Portland cement and/or other pozzolanic materials.

Over 15 years ago, Peakward started to export blast-furnace slag in international construction market. We have now expanded our operation to more than ten countries. Our slag is used mainly for producing Slag cement and ready-mix concrete. We can supply GGBFS & GBFS from various countries including Japan, China, Vietnam, Korea, India etc. The BF Slag supplied by us have almost 90%-96% Glass content and soft to grind. GBFS is supplied in bulk while GGBFS is supplied both in big bags and in bulk .
