New 'Green' Geopolymer Concrete Delivers
Win-Win for Industry and the Planet
By Jeff Salton
Concrete is the most prevalent building material on the planet, and though the world would be pretty flat without it (not many tall buildings and structures), it does come at a price – around 5-8 percent of all human-generated atmospheric CO2 comes from the concrete industry. A culprit is Portland cement, the binding agent in concrete. It's the most widely produced man-made material on earth. Production of Portland cement is currently exceeding 2.6 billion tons per year worldwide and growing at 5 percent annually. To halt these alarming pollution figures, innovative research on geopolymer concrete, along with ways of using a waste byproduct from coal-fired power plants, is being conducted by Dr Erez Allouche, assistant professor of civil engineering at Louisiana Tech University and associate director of the Trenchless Technology Center.
