@SLCPL is a five-story-tall, wedge-shaped building. During the 2003 project of building this immaculate space, Boral Resources (Now Eco Materials) provided ultra-fine pozzolan for the exposed concrete surfaces.
Saluda Dam is a hybrid of a rockfill berm on the downstream slope and a new roller-compacted concrete (RCC) gravity dam downstream of the dam. Fly Ash is essential to the mix of RCC, it improves the workability.
The bridge spans approximately 4.5 miles, this project was one of the largest public works projects in California history. The project used approx. sixty thousand tons of Fly Ash. According to @GWR, it is the widest bridge as of 2013.
