ACI has over 94 chapters, 244 student chapters, and 30,000 members spanning over 120 countries.


The C12 Framework for Building Great Business for a Greater Purpose.

Each day, business leaders face challenges, opportunities, and decisions with significant downstream impact. This considerable responsibility may cause them to feel lonely at the top. The weight can be immense, but so is the reward—particularly in pursuit of honoring God by how they run their companies. Eliminating the daylight between our14 faith and work requires diligence.

For three decades, C12’s singular focus has been to create a framework that compels and equips Christian business leaders to achieve excellence through the power of peers.


The Volumetric Mixer Manufacturers Bureau (VMMB) has five charter members, which manufacture continuous volumetric mixers or concrete mobiles, mobile mixers, shake and bake trucks, and the like. Contractors and concrete producers operate these volumetric mixers, and many of these concrete trucks go to government agencies and foreign buyers to produce specialty concrete.

The ingredients for a batch of concrete are loaded into individual compartments on the mobile mixer and driven to the job site. Upon arrival, the concrete is mixed and immediately placed.

VMMB began in November of 1999, with the assistance of the National Ready Concrete Association (NRMCA). The three main purposes of VMMB are: to remain in conjunction with ASTM and ACI standards, to promote the use of the equipment through education and awareness, and to improve the professionalism of the manufacturers and operators of mobile mixers.

ASTM International is a globally recognized leader in the development and delivery of voluntary consensus standards. Today, over 12,000 ASTM standards are used around the world to improve product quality, enhance health and safety, strengthen market access and trade, and build consumer confidence.

Our leadership in international standards development is driven by the contributions of our members: more than 30,000 of the world’s top technical experts and business professionals representing 140 countries. Working in an open and transparent process and using ASTM’s advanced IT infrastructure, our members create the test methods, specifications, classifications, guides and practices that support industries and governments worldwide.
