A new dedicated slag silo is fully integrated with Canal Block\u2019s batching system, which is programmed to quickly switch between binder types.<\/p>\n\n\n\n SEAMLESS ADOPTION<\/strong><\/p>\n\n\n\n Kraft Curing Systems unveiled the CO2<\/sub>\u00a0chamber concept at the 2025 Precast Show in Indianapolis. Approaching their first commercial installation of such equipment, company engineers configured chambers to readily accommodate Canal Block\u2019s pallet rack transfer and crawler rail equipment. The chambers operate at atmospheric pressure and feature insulated metal sandwich panel walls to minimize energy and CO2<\/sub>\u00a0loss.<\/p>\n\n\n\n The CarbiCrete production plan included the installation of an external pressure vessel to charge the chambers; it imparts CO2<\/sub> in two to three hours depending on target gas levels and curing loads. Precision gas analysis instruments integral to Kraft Curing controls track injected CO2<\/sub>\u00a0volumes, while mass flow meters yield absorption and sequestration data.<\/p>\n\n\n\n \u201cThe challenge found in this project was integrating cutting-edge CO2<\/sub>\u00a0curing technology, the required curing enclosures and equipment in traditional block plant infrastructure,\u201d says Kraft Curing Systems Managing Director Michael Kraft. \u201cWorking together with Carbicrete and Canal Block, both professional and innovative partners, we were able to achieve excellent results.\u201d<\/p>\n\n\n\n Canal Block is the second North American CarbiCrete partner. It introduced low carbon block to the Ontario market through an initial supply arrangement with Patio Drummond, Quebec peer and inaugural CarbiCrete partner. Patio Drummond has also supported early CarbiCrete block distribution in the U.S. through Maine\u2019s Gagne & Son Concrete Products.<\/p>\n\n\n\n Canal Block and CarbiCrete are compiling carbon volume figures to support an environmental product declaration for Port Colborne plant output. Its global warming potential metrics are poised to be far below those of conventional CMUs, based on GWP factors indicated in Patio Drummond\u2019s premier CarbiCrete block EPD.<\/p>\n\n\n\n CarbiCrete\u2019s first overseas partner is POINT.P, which plans a 2026 opening for a low carbon block production line at its Hauts-de-France plant north of Paris. A key building materials producer and retailer in France, POINT.P is a sister business of Chryso Inc. under Saint-Gobain Group, Paris. \u2014 Kraft Curing Systems GmbH, Lindern, Germany, www.kraftcuring.com; CarbiCrete, Lachine, Quebec, www.carbicrete.com<\/p>\n\n\n\n Commercial scale CarbiCrete block production at Port Colborne necessitated the addition of dedicated slag cement silo (opposite page) and pressurized carbon dioxide vessel (left background in lower photo), engineered and calibrated to charge the curing chamber over two- to three-hour cycles.
