No cement in the UK has lower embodied CO2

 

Our ongoing commitment to sustainability has seen the Lafarge Group ranked in the Top 100 Most Sustainable Corporations in the World for the past 6 years - and CEMERGI marks our most valuable contribution to sustainability yet.

 

A unique mix of portland cement and ground granulated blast furnace slag, only CEMERGI comes with the perfect blend ready mixed and ready for immediate use.

THE HARD FACTS

CEMERGI is a factory produced Blastfurnace cement suitable for most applications

CEMERGI is a Blastfurnace cement which conforms to BS EN 197-4 CEM III/A 42,5L with a minimum blastfurnace slag content of 50%. It is a quality assured cement with independent third party certification and carries a CE mark.

 

Applications

CEMERGI contains a controlled blend of Portland cement and ground granulated blastfurnace slag. It is recommended as a sustainable alternative to Portland cement for most applications including civil engineering, building, ready-mixed concrete and concrete products.

 

Properties

The properties and workability of CEMERGI concrete compared with Portland cement concrete at the same cement content and workability are:

  • Similar in 28 day compressive strength.
  • Improved workability retention.
  • Reduced effective alkali content. Recommended for use with high reactivity aggregates including recycled aggregates. Improved sulfate resistance, CEMERGI is classified by BS 8500 as CEM III/A+SR.
  • Extra care is required with curing concrete in order to realise the full potential strength and longterm durability of the concrete.
  • Reduced heat of hydration.
  • Slightly lighter in colour. Freshly exposed concrete may exhibit a slight blue-green tinge, this is not uncommon and will fade and disappear with exposure to the atmosphere leaving the lighter colour associated with CEMERGI concrete. The original discolouration will not recur.
