Sources: University of Tokyo; CP staff University of Tokyo researchers have unveiled the concrete thermal gravimetry and gas analyzer, a boxlike device gauging carbon dioxide absorbed in hardened specimens. A concrete block placed inside the device is heated to 980°C, releasing CO2 and other readily measured gases. The process takes about one-third of the time of the current measurement method, which…

Graphene for Carbon-Neutral Concrete
Graphene technology promises carbon-neutral ready mixed concrete. Those seeking to aggressively push a transition to carbon neutrality should look to Adam Smith, known as the father of capitalism, for guidance. According to the 18th-century Scottish philosopher and economist, “By pursuing his own interest [the individual] frequently promotes that of the society more effectually than when he really intends to promote…

Eco Material Technologies will add up to 600,000 tons to its annual concrete-grade fly ash shipments with construction of a facility for processing and beneficiating coal combustion material impounded at Georgia Power’s Plant Branch, a Putnam County, Ga. generating station the Atlanta-based utility retired in 2015. Using its ES EcoSystem Efficient Carbon Offloading (ECO) technology, South Jordan, Utah-based Eco Material…
Read MoreCalifornia producers’ carbon volley
Two years of major gestures surrounding greenhouse gas emissions in cement and concrete production or procurement solidify California’s reputation for incubating policy. In October 2021, the California State Senate passed SB 596, charting a regulatory course for Golden State cement producers to attain net-zero carbon operations by 2045. The California Nevada Cement Association concurrently published an SB 596 action plan,…
Read MoreDOE confirms cement industry’s near-term CO2 emissions reduction
U.S. Department of Energy Deputy Secretary David Turk led off a Climate Week New York City session last month noting how proven processing approaches will enable cement producers to book a 30 percent greenhouse gas emissions reduction by the early 2030s and perhaps an additional 10 percent cut by 2050. The metrics set an upbeat tone for the Portland Cement…
