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 powerplants, is being conducted by Dr Erez Allouche, assistant professor of civil engineering at Louisiana Tech University and associate director of the Trenchless Technology Center.

A greener alternative, inorganic polymer concrete (geopolymer) fits into an emerging class of cementitious materials that utilize ‘fly ash’, one of the most abundant industrial by-products on earth, as a substitute for Portland cement.

  1. I have access to massive amounts of wood pellets, fly ash, illite clays,mine tailings and cellulose fiber.
    I am interested in mining geopolymer concrete, paint, ceramics, fiber board and energy products.
    I have massive amounts of catalysts for catolic hydrothermal of waste into hydrogen. My company is always interested in nanotechnology using only safe non-toxic and non costic products in the manufacture process.
    Contact me via email for any innovative technology which you think we may have any interest.
