Uses and applications of blast furnace slag lumps
- Road construction: sub-base and base layer aggregate in place of crushed stone.
- Fill and embankments: land filling and levelling of plots and yards.
- Concrete and blocks: crushed slag used as aggregate after suitability testing.
- Cement and mineral wool: raw material input in some cement and slag wool plants.

Frequently asked questions about Blast Furnace Slag Lumps
What are blast furnace slag lumps?
They are air-cooled slag from iron making blast furnaces. The slag solidifies into hard, stone-like pieces.
What is the difference between slag lumps and granulated slag?
Lumps are cooled slowly in air and become crystalline and hard. Granulated slag is quenched with water into sand-like glassy grains and is mainly used in cement.
Can slag be used in road work?
Yes. Air-cooled slag is used as sub-base and base aggregate. Test it against your project specification before use.
Do you crush slag to size?
Crushed and screened sizes can be arranged. Share the size range and quantity for a quotation.
