Concrete Facts | C4E Presents #041

Marija Krstić, assistant professor of practice in the Department of Civil Engineering at Stony Brook University, is interested in cement production, which is a major source of global carbon emissions. Host Heather Lynch and Krstić explore the difference between cement and concrete, why steel reinforcements are essential for structural concrete, and how Portland cement – the binder, or glue in concrete production – requires high kiln temperatures, which releases CO2. Krstić explains why it is still unlikely that concrete is to be fully replaced with sustainable alternatives and changed methods in the near future. Learn more with:“Field-Application-of-Recycled-Glass-Pozzolan-for-Concrete,” by Marija Krstić and Julio F.
