Volumetric concrete mixers have evolved significantly since their inception in the mid-1960s, when companies began developing their own versions to meet growing construction demands. The establishment of the Volumetric Mixer Manufacturers Bureau (VMMB) in 1999 marked a milestone in standardizing and advancing the industry. Over time, these mixers have incorporated innovations such as precision technology, automation, and versatile features like color mixing and fiber systems, enhancing efficiency and quality. Today, they are prized for their cost-effectiveness and flexibility, with steady growth projected in North America due to their clear advantages over traditional mixing methods.
Key Points Explained:
-
Origins in the Mid-1960s
- The history of volumetric concrete mixers traces back to the mid-1960s when companies started building their own versions. This period marked the beginning of on-site concrete mixing solutions, addressing the need for flexibility and reduced waste in construction projects.
-
Formation of the VMMB (1999)
- In 1999, the Volumetric Mixer Manufacturers Bureau (VMMB) was established as a trade association. This organization played a pivotal role in unifying industry standards, promoting innovation, and ensuring quality across manufacturers. The VMMB’s creation reflects the growing recognition of volumetric mixers as a viable alternative to traditional batch plants.
