Contractors, equipment dealers and a curious public turned out for World of Concrete 2018 in Las Vegas on Jan. 23. With the U.S. construction market showing signs of improvement, crowds were cautious but still eager to see the latest in construction equipment from the more than 1,500 exhibitors on site. Live demonstrations and hands-on opportunities to mix, polish, break and crack concrete are a hallmark of the show, which is expected to draw over 55,000 attendees this year over the course of the week.
