But is fly ash from coal power plants a safe substitute? Can Concrete Save Us? Locking Up Carbon in Building Materials Concrete is responsible for a huge proportion of global carbon dioxide emissions. A few companies want to reverse this cycle by sequestering carbon in building materials. CarbonCure-Capturing Carbon in Concrete Blocks Ductal-Stretching the Performance and Durability of Concrete EPA Finds Coal Fly Ash Safe in Concrete and Gypsum Wallboard Industry-Average Impacts of Concrete Revealed in EPD The industry-wide EPD for concrete shows impacts by U.S. region and meets LEED v4 requirements for a new material credit. Using Fly Ash in Concrete Fly ash lowers the environmental footprint of concrete and improves durability. Pouring and curing concrete with high levels of fly ash requires special treatment. Setting Carbon Footprint Rules for Concrete Impact of Concrete Extends to Sand and Gravel Production Portland cement takes a lot of heat for concrete’s carbon emissions, but water quality, land use, and transportation count too, especially because of aggregate.
