Ensuring Resilience in High Traffic Elements
Location: Berkeley, California Dates Poured: May 9, 2025At the University of California, Berkeley, history and innovation are converging. Switch Station 8, a structure originally constructed in 1904 as a power plant and later transformed into an art museum, is undergoing another transformation. This time into a substation that will enable the university to generate clean energy by 2030.
Fortera supplied ReAct® Blend for critical high traffic elements of the project which require proven resilience, including two main entrances, a staircase, and an outdoor recycling receptacle area. The mix incorporated a total supplementary cementitious material (SCM) content of 56%.

“The fresh-state properties of the concrete containing 12% Fortera ReAct Blend demonstrated impressive workability, was easy to both place and finish and performed very well at the Berkeley Substation 8 Project. It looks excellent in its hardened, finished state too, having a very light albedo.”
