Concrete is the most popular building material in the world, and we use between 10 and 30 billion tons each year. But the price of that progress is a cost to the environment: Cement, an essential ingredient in concrete, is responsible for 8 percent of global anthropogenic greenhouse gas emissions. Enter the power of artificial intelligence. Researchers at the University of Illinois Urbana-Champaign, Meta, and concrete supplier, Ozinga, partnered on discovering better concrete formulas using AI. The early-stage results found the AI-powered formulas reduce the carbon footprint of the concrete by 40% while maintaining strength and durability. Meta tested the formulas on multiple structures at the company’s DeKalb data center, namely the floor slabs of the guardhouse and construction management team’s temporary offices.
