“This research article provides an overview of the benefits of zeolite in concrete including increased strength. The article does not talk about the massive decrease in the carbon footprint of zeolitic concrete based on the fact it absorbs CO2 from the air and from the reduction of hydrocarbons needed to “cook” Portland Cement. Zeolite gets its cementing characteristics without being roasted at 1,400 degrees Celsius.” Steve Harpur
