CEM –III Blast Furnace Cement

Blast Furnace Cement (BFC) is created through the addition of blast furnace slag with Portland cement clinker and gypsum. BFC is used to make durable concrete structures around the world. BFC has been widely used in Europe and increasingly in the US and Asia, extending the lifespan of buildings from 50 years to 100 years. Shah Cement- Blast Furnace Cement surpasses the requirements of BDS EN 197-1: 2003 CEM-III/A, 32.5 N.

Functional Benefits


The use of slag cement has demonstrated long-term performance enhancements allowing designers to reduce the environmental footprint of concrete while ensuring improved performance and increased durability. Concrete containing BFC is less permeable, has lower hydration, higher ultimate compressive strength, is resistant to sulfate-acid attack and aggressive chemicals, resistant to many forms of deleterious attack to alkali-silica reaction and has better workability and finishing ability than normal concrete.


Concrete containing BFC has a higher ultimate strength. It has a higher proportion of the strength-enhancing calcium silicate hydrates (CSH). Concrete made with BFC continues to gain strength over time.

Economical & Environmental

In recent years, there has been significant growth in the production and sale of BFC. The manufacture of BFC requires less energy than that needed for the production of OPC, making it cheaper to produce and a more viable option in a downturn economy.


Blast Furnace Cement can be used in the most aggressive environments, such as exposure to chlorides and sulphates, meaning it is longer lasting in marine, agricultural and chemically aggressive environments.
