National Ready Mixed Concrete Association

Stephen Stepanian, chairman of the NRMCA for 1943-1944, was honored on the American Road & Builders Association’s list of the Top 100 Private Sector Transportation Construction Professionals of the 20th Century. Stepanian, an Armenian immigrant, in 1914 designed the self-discharging, rotating drum mixer unit that revolutionized the concrete industry.

“Mr. Stepanian’s genius and foresight has led to what is now the most recognizable piece of specialty equipment in the construction industry, says NRMCA president Robert Garbini.” Today, thanks to our former chairman, more than 70,000 ready mixed concrete trucks travel every day throughout the U.S., making concrete the foundation of the nation.”
