Embodied Carbon 101 & Low-Carbon Concrete in Tilt-Wall Construction
Duration: 53 minutes
Speakers: Erika Winters-Downey, S.E., LEED AP BD+C | Kyle Kammer
This presentation will start with an introductory segment on Embodied Carbon 101, providing a foundational understanding of the environmental impact of construction materials. The session will then delve into the practical application of low-carbon concrete mix designs in the context of schedule-driven tilt-wall construction. Typically, high early-strength concrete mixes are used to facilitate the rapid tilting of wall panels, often within 3-7 days after pouring. However, integrating Supplemental Cementitious Materials (SCMs) can slow the strength gain process. In 2023, a collaborative effort between Clayco, Concrete Strategies, Wiss Janney Elstner engineers, Ozinga ready-mix, Breakthrough Energy, and Climate Works foundations tested various carbon-reducing mixes under challenging winter conditions. This talk will cover the tested mixes, lab and field results, feedback from crews on handling the mixes, and future plans for incorporating low-carbon solutions in tilt-wall construction.

About the Tilt-Up Concrete Association
Founded in 1986, the Tilt-Up Concrete Association (TCA) strives to improve the quality and acceptance of site-cast Tilt-Up construction - one of the fastest growing industries in the United States, combining the advantages of reasonable cost with low maintenance, durability, speed of construction and minimal capital investment. Over 10,000 buildings, enclosing more than 650 million square feet, are constructed each year using this construction method.
