Some of our work here at Ohio State (in projects led by Cansu Acarturk and Anthony Wong) has focused on understanding and enabling greater use of this more-sustainable cement type, which also has other amazing properties including rapid strength gain, and expansive properties (which help reduce cracking).
In this talk, Susan Foster-Goodman, from CTS Cement will give an industrial perspective on the applications and benefits of using calcium sulfoaluminate cements.

The goal of my work is to reduce the environmental impact of cementitious binders by understanding the mechanisms that control development of high performance materials, and to improve our environment through innovate uses of cement and concrete.
More specifically, I am interested in:
- Understanding the influence of chemical composition and phase content on performance of cementitious materials systems.
- Developing and optimizing new cement formulations with smaller CO2 production footprints.
- Understanding the physical and chemical processes involved in durability issues such as sulfate attack, alkali silica reaction, and damage resulting from freezing and thawing.
- Investigating methods for prevention of distress, and when it occurs, repairing and rehabilitating structures affected by durability issues.
- Increasing utilization of cement fillers (such as fly ash and natural pozzolans) in concrete mixtures to offset landfilling while lowering construction costs.
- Determining the feasibility of upscaling new systems for use in large scale structures (moving discoveries from the lab into real world usage).
- Understanding use of rapid repair materials in construction to decrease construction time and costs.
- Locating new settlements of Rebarus concreties, to ensure we have enough to continue meeting U.S. urban infrastructure needs: https://www.reddit.com/r/shittyaskscience/comments/50npyj/how_do_people_find_concrete_foundations_to_build/
