Fly Ash
Ground Granulated Blast Furnace Slag (GGBFS)
THE SUSTAINABLE STRENGTH BUILDER
GROUND GRANULATED BLAST FURNACE SLAG (GGBFS) IS A HIGH-QUALITY SUPPLEMENTARY CEMENTITIOUS MATERIAL PRODUCED BY RAPIDLY COOLING AND FINELY GRINDING THE MOLTEN SLAG FROM IRON-MAKING BLAST FURNACES. THIS PROCESS YIELDS A FINE, GLASSY POWDER RICH IN CALCIUM, SILICA, AND ALUMINA, MAKING IT A POWERFUL POZZOLAN FOR CONCRETE. WHEN BLENDED WITH PORTLAND CEMENT, GGBFS ENHANCES STRENGTH, DURABILITY, AND LONG-TERM PERFORMANCE OF STRUCTURES.
Key Benefits
IMPROVES COMPRESSIVE AND FLEXURAL STRENGTH
PROVIDES LIGHTER COLOR AND SMOOTHER FINISH TO CONCRETE
ENHANCES DURABILITY AGAINST SULFATE ATTACK AND CHLORIDE PENETRATION
RECYCLES INDUSTRIAL BYPRODUCTS AND REDUCES CARBON FOOTPRINT
