A breakthrough process for ready mixed gives John Cook, director of Technical Services at Atlanta’s Thomas Concrete, cause for enthusiasm this construction season. In late February, he and his team oversaw the installation of the CarbonCure Ready Mixed Technology at their Doraville, Ga. plant. They immediately began the process of lowering cementitious material content and dosing concrete mixes with carbon dioxide (CO2) gas using the CarbonCure injection system. Later in March, Cook and colleagues eagerly reviewed the 28-day strength data and confirmed: CO2 may be used as a viable cement replacement.Read More

Vulcan Materials is the first ready mixed producer to license technology in which industrial process-sourced carbon dioxide is injected into fresh concrete mixes, thereby offsetting water requirements; forming additional limestone in the matrix; and, sequestering the greenhouse gas in a hardened slab or structure.Read More
Wally Hernandez has joined Besser Co. as sales and technical support representative, based in Florida and responsible for the entire product line. A Dominican Republic native, he moved to Florida at the age of 11 and, after graduating from high school, completed a tour of duty with the Marines, working in helicopter hydraulics maintenance.
Ernest Maier has added the CarbonCure technology to its Maryland concrete masonry operation, and is poised to be the first Washington, D.C., market operator to issue Environmental Product Declarations and Health Product Declarations for block. An EPD covering CMU processed with a carbon dioxide-based curing system will time with the ongoing implementation of the District of Columbia’s Green Building Act, the first local law requiring new, private buildings to meet LEED rating system standards. EPD will especially factor into projects for which certification under the new LEED v4 is targeted.Read More
