RWC GGBFS or Ground Granulated Blast Furnace Slag is a specialized product, typically utilized in activation of granular pavement materials & as a cementitious material in the manufacturing of concrete.

Concrete containing GGBFS has a higher ultimate strength than concrete made with Portland cement only.

Its by-product of iron and is obtained by the heating of iron ore, limestone and coke at a temperature about 1500°C. The process is carried out in a blast furnace, a partial replacement of OPC cement in concrete production at batching plants.

Its highly cementitious and high in calcium silicate hydrates (CSH) which is a strength enhancing compound which improves the strength, durability and appearance compared to Portland Cement production.

When added to concrete, its acts as a stabilizing agent and improves the quality of concrete.


RWC GGBFS can be used in many constructions product as follows:

  • High resistance to chemical impacts.
  • High resistance to sulphate.
  • High durability.
  • High ultimate strength.
  • High workability.
  • Low hydration heat
  • Low shrinkage
  • Low permeability
  • Low Carbon Emissions
