Because of the short life of ready mixed concrete, the industry is necessarily dependent on local producers. There are two types of ready mixed concrete plants: central plants (sometimes called "wet" plants) and dry-mix (traditional) plants. Fully loaded, a truck may weigh as much as 60,000 pounds and contain as much as 20 cubic yards of concrete (National Safety Council 1986). Truck drivers are key industry employees who are responsible for delivery of concrete to the worksite and maintaining of concrete quality during transfer from plant to site. Because the data sources for this analysis are not a representative statistical sample for the ready mixed industry, the findings here do not necessarily exactly reflect the hazards in the industry; for instance, the types of injuries might occur in a different order than shown here if all injuries were counted.

Fully loaded, a truck may weigh as much as 60,000 pounds and contain as much as 20 cubic yards of concrete (National Safety Council 1986). Truck drivers are key industry employees who are responsible for delivery of concrete to the worksite and maintaining of concrete quality during transfer from plant to site. Concrete formulations are dictated by the type of structure to be built. Weather conditions also have an impact on the proportion of water, admixtures, and water temperature used. (National Ready Mixed Concrete Association 1995) Concrete plants are located in areas convenient for deliveries of raw materials (cement, sand, gravel, other aggregate which are often brought to.
