AGI's Premium Coal Ash — Class F
The Next Generation in Concrete

Green concrete is a form of eco-friendly concrete manufactured with products like Coal Ash which reduces carbon foot print during the concrete ready mix process. 


When used in concrete mixes, Coal Ash:

  • improves the strength and durability

  • improves the segregation of the concrete and makes it easier to pump = improved "workability"

  • is more resistant to corrosion and premature deterioration

  • for each pound of fly-ash used, one pound of carbon dioxide emissions will be saved​

In Hawaii our Coal Ash is exclusively distributed through Hawaiian Cement.

AGI Ground Granulated Blast Furnace Slag – Grade 100

Slag cement is a hydraulic cement formed when granulated blast furnace slag (GGBFS) is ground to suitable fineness and is used to replace a portion of portland cement. It is a recovered industrial by-product of an iron blast furnace. 

The benefits of using slag in cement include:

  • Higher long-term compressive and flexural strengths

  • Low permeability, provides good resistance to chloride and sulphate attack which is present in seawater

  • Improved durability and resilience

  • More consistent performance

  • Lighter color

  • Reduces the environmental impact of concrete mixtures by decreasing carbon footprint
