The Concrete Plant Manufacturers Bureau was formed in 1958 and incorporated in 1961, bringing together in one organization representatives from all of the key manufacturers of concrete plant equipment at the time. The vision behind the development of the Bureau was and continues to be much like other not-for-profit associations - work together to achieve what we cannot do separately.
CPMB member companies are directly involved in the design, manufacture and sale of concrete plants and plant components. In 1965, the Bureau added a division for plant mixers (called the Plant Mixer Manufacturers Division). In 1976, a second division for the control systems used on plants (Control Systems Manufacturers Division) was added to the Bureau. Most recently, in 2000, a new division for dust collection equipment (Air Quality Manufacturers Division) was added to the membership. All of these Divisions work in tangent with the Bureau to ensure that these specialized components are represented in all of the Bureau's work.
The primary function of the CPMB is to establish minimum standards for rating various components of concrete plants for the protection and assurance to the user that the plated components of the plants conform to these Standards.
The CPMB also provides a means for members to come together on matters common to the concrete industry where concrete plant technology, user services, agency specifications and related common problems can better be served through coordinated efforts of the members of the CPMB and its Divisions. The Bureau has done significant work in the areas of safety, the environment, proper maintenance and operation procedures, and the like. Members frequently participate as instructors at National Ready Mixed Concrete Association (NRMCA) functions such as NRMCA's ConcreteWorks Conference & Expo, the CONEXPO-CON/AGG Show, the NRMCA Convention, and any other occasions where sharing their expertise can be of benefit to the ready mixed concrete industry.
