Truck Mixer Manufacturers Bureau (TMMB)
TMMB is an association of ready mixed concrete truck manufacturers who have joined together in support of the ready mixed industry. TMMB members are required to manufacture equipment in accordance to the TMMB Standards. These Standards have requirements for both volume and performance of the equipment. Each member has tested their equipment to verify that at the time of manufacture, it mixes concrete in conformance with ASTM C 94. TMMB also offers several complimentary publications for ready mixed producers. Please visit the Publications section on this Web site to order yours.
Concrete Plant Manufacturers Bureau (CPMB)
The Concrete Plant Manufacturers Bureau was formed in 1958 and incorporated in 1961, bringing together 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. 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. CPMB offers several complimentary publications for ready mixed producers. Please visit the Publications section on this Web site to order yours.
Volumetric Mixer Manufacturer Bureau (VMMB)
Organized in November 1999, VMMB is an organization of manufacturers of continuous volumetric mixers, sometimes known as concrete mobiles, mobile mixers, shake and bake trucks and the like. This equipment is usually mounted on a truck, although it can also be built in stationary plants and trailer mounted units. VMMB was formed to: 1) to develop, in conjunction with ASTM and ACI, a standard for which this equipment can be rated; 2) to promote the use of this equipment through education and awareness; and 3) to improve the professionalism of both the manufacturers and operators of mobile mixers.
