GGBS
GGBS is a by-product from steel plants obtained from blast furnaces, during the separation of iron from iron ore. The process involves cooling of the slag through high-pressure water jets, which enables the formation of granular particles. The granulated slag is further processed by drying and then grinding in a vertical roller mill or rotating ball mill or roller press to a very fine powder, which is called GGBS.
Key Features
- A sustainable material for green building construction.
- Replacing Portland cement with GGBS helps in reducing CO (carbon monoxide) emissions
- By using GGBS water demand decreases which further reduces capillary pores.
- GGBS is slower to react with water than OPC which will help to give more time to place concrete.
- The rate of heat evolution associated with GGBS is reduced which will reduce the thermal crack
- GGBS increases compressive strength because GGBS has higher activation energy than OPC.
- GGBS gives a better finish.
Availability
GGBS is available in bulker as well as bags.
