Carbon Negative Concrete

• Concrete is the most widely used man-made material
• Concrete is made of Cement, Water & Aggregate
• Concrete can be a significant contributor of CO₂

   - Traditional Concrete: 537 lb CO₂/yd³
   - Calera Concrete: -1,146 CO₂/yd³

Cubic yards of concrete used to build...
A house: 200
A hospital: 7,500
Denver International Airport: 2,500,000
Grand Coulee Dam: 8,500,000
If the Grand Coulee Dam had been built from Calera concrete, there would be 7 million less tons of CO₂ in the atmosphere.
