ACI recognizes excellence in concrete innovation

The American Concrete Institute honored 12 concrete projects at the 2017 Excellence in Concrete Construction Awards gala during the Institute’s convention in Anaheim, Calif. The overall winner was R•torso•C, a concrete minimalist residence in Tokyo. The Excellence in Concrete awards program was created to honor the visions of the most creative projects in the concrete industry, while providing a platform to recognize concrete innovation, technology, and excellence across the globe. In order to be eligible for participation in the Excellence Awards, projects needed to be winners at a local ACI Chapter level and submitted by that Chapter, or chosen by one of ACI’s International Partners.

The concrete for R•torso•C was composed of a compound mix called shirasu—volcanic ash found in southern parts of Japan. The material increases in durability over time while also providing deodorizing qualities.

It took 12 months and more than 1750 cu. yd. of concrete to bring the Market Street Parking Garage (above) in downtown Wichita, Kan., back to life. The city reclaimed 550 parking spots at a fraction of the cost it would have taken to demolish the deteriorated garage and construct a new one.

The Ryerson University Student Learning Centre in Toronto is LEED Silver compliant. While the concrete structure is visibly rugged and heavy, the glass skin of the building is lightweight and transparent. A frit pattern emphasizes this delicate nature while also creating varying lighting qualities within the interior.
