Relevant Information
Sustainability
Cemex cement, combined with Ground Granulated Blast Furnace Slag (GGBS), supports compliance with the Dubai Green Building System (Al Sa’fat – 2nd Edition). This solution lowers embodied carbon, improves durability, and enhances energy performance—helping projects achieve Silver, Gold, or Platinum ratings with confidence.
Workability
GGBS are great to work with. You’ll find them easier to handle, pump and place with precision – even in adverse weather conditions. And their chemical composition reduces the risk of problems and unwanted chemical reactions.
Improved handling
• Less water required for a given workability.
• Better pumping properties due to increased cohesion of the mix.
• Easier to compact.
Chemical features
• Less free lime content reduces permeability and promotes long term strength.
• Reduced alkalinity of concrete minimises risk of alkali-silica reaction.
• Lower heat of hydration reduces risk of early-age thermal cracking.
Enhanced working window
• Longer setting time means more time for getting the right finish.
• Helps you avoid cold joints, a major benefit for large or mass concrete pours.
