The returned concrete is either crushed and used as road base, made into blocks, or simply discarded. All these sce- narios require additional time, fuel use and a duplication of the load of concrete. Because Verifi software monitors concrete consistency in transit, and controls precise injections of water or admix- tures en route, the concrete is delivered more consistently within performance specifications. Early data indicates that this could reduce rejection rates from 5 percent to 3.8 percent – saving time, money and materials. Since a typical concrete load represents 5,500 lb. of carbon dioxide emissions, reducing concrete waste also benefits the environment. 3. Fuel efficiency. In ready-mixed concrete delivery, fuel use is a significant source of cost and environmental impact. Approximately 23 percent of fuel in a concrete delivery is used for high-speed drum rotations that mix the concrete. The timing of these rotations is typically controlled by the truck driver – based on minimal information about con- crete consistency or fuel efficiency. In contrast, Verifi soft- ware gives the driver instructions on the optimal number and timing of rotations. Early data suggests that the num- ber of high-speed revolutions can be reduced by 10 per- cent, representing significant cost reductions and associat- ed environmental benefits. The advantages described above reduce cost, maintain crit- ical performance specifications, and significantly improve environmental performance. In addition, truck drivers using Verifi software have less need to climb a ladder next to a spinning drum – a clear and important safety benefit. Key Audiences With this new category-creating technology, concrete pro- duction can shift from an inexact and manual process to a precise and automated one. With that shift comes the ability to provide consistent quality concrete while sav- ing time, money, materials and energy. Not only does this benefit our customers, it also benefits our society and our planet.
