Cemen Tech, one of the founding members of the Volumetric Mixer Manufacturers Bureau (VMMB) announces the successful testing of a volumetric mixer. The Volumetric Mixer manufacturer’s Bureau (VMMB) is an affiliate of The National Ready Mix Concrete Association (NRMCA).

The primary mission of the Volumetric Mixer Manufacturers Bureau (VMMB) is to provide standards for Manufactures ensuring quality built mixers that meet or exceed accepted industry standards. In addition, the VMMB promotes the use of volumetric mixers and provides support for the owners and manufacturers who work in this industry. 

In an effort to further their mission and demonstrate the versatility and quality of concrete produced from volumetric mixers the VMMB recently sanctioned tests to be completed with both a volumetric mixer and a traditional drum mixer. The tests were conducted by Custom Crete Inc. an Old Castle company the world largest owner of volumetric mixers (owners of Cemen Tech equipment) out of Dallas Texas. Testing for both types of mixers was simultaneously done by Terracon labs as they conducted the test in accordance with ASTM specifications.  Data for slumps, air content, concrete temperature etc were all measured accordingly and the test data was completed and finalized with the traditional break tests.

Numerous test cylinders and samples were taken and revealed that on average the strength of the concrete produced from the volumetric mixer averaged 4300 psi vs. the drum which averaged 3990 psi on twenty-eight day cylinder break sample. Seven day breaks showed the volumetric mixer averaged 3440 psi vs. the drum mixers 3030 psi.  The popularity of volumetric mixers continues to grow as they compliment many drum operations through out the world.
