A consortium of design, construction, and material industry partners came together in late 2023 to evaluate a challenge increasingly shaping the future of concrete construction: how to meaningfully reduce embodied carbon while still meeting the demanding schedules required for modern tilt-up delivery.<\/p>\n\n\n\n

The result was a focused field testing program in St. Louis, Missouri centered on experimental low-carbon tilt-wall concrete mixes designed specifically for fast-track applications. The effort ultimately received Honorable Mention in the inaugural TCA Achievement in Sustainability + Resilience Award<\/a> program.\u00a0<\/p>\n\n\n\n

Led collaboratively by teams from Clayco Construction, Concrete Strategies, Wiss, Janney, Elstner Associates (WJE), Ozinga Concrete, Kienstra Concrete, Amazon Web Services, Breakthrough Energy, and ClimateWorks Consulting, the program sought to evaluate whether lower-carbon concrete mixes could achieve the early strength performance necessary for schedule-driven tilt-wall construction.\u00a0<\/p>\n\n\n\n

Tilt-up construction schedules often require wall panels to be erected within days of placement. Traditional high early-strength concrete mixes are commonly used to support these timelines, with panels sometimes lifted as early as three days after casting. However, many low-carbon concrete strategies rely on supplementary cementitious materials (SCMs), which can alter traditional strength gain curves and raise concerns about schedule compatibility. <\/p>\n\n\n\n

To evaluate performance under realistic field conditions, the team produced and monitored three separate tilt-wall panel mixes:<\/p>\n\n\n\n
