TCA Research

Latest Research

In 2021, TCA completed the final phases of its CRED research at Tennessee Technological University: Going Beyond ACI 332: Commercial / Residential Enhanced Durability Concrete: Phase III The Effect of Limited Curing.

2020 Research

TCA undertook its first practical research efforts in 2020 including the Cylinder Curing Study. We also continued our CRED research with the release of Going Beyond ACI 332: Commercial / Residential Enhanced Durability Concrete: First Look.
