# Meaning of concrete mixer capacity.3

## Meaning of concrete mixer capacity.

(OP)
Dear sirs,

Meaning of capacity rating of concrete mixer I am intetested in.

### RE: Meaning of concrete mixer capacity.

Typically it is the maximum volume of concrete that can be properly mixed in the mixer. I assume this is a stationary mixer not a transit mixer since the capacity is quite large.

You can mix any volume up to and including the maximum stated capacity.

### RE: Meaning of concrete mixer capacity.

generally speaking the capacity of a mixer in cu.m. is the quantity (in volume) of aggregates+sand+cement you can load into the mixer. The production of concrete (after compaction) is 70% of loaded volume. For example if you load 10 cu.m. of aggregates, you will produce 7 cu.m. of placed/vibrated concrete

### RE: Meaning of concrete mixer capacity.

robyengIT.....that's a bit misleading and confusing. The aggregates occupy about 70 percent of the absolute volume of each cubic meter of concrete. You still have to add the other constituents to create a concrete mix of 1 cubic meter. The capacity of the mixer is the volume of concrete, not the volume of the aggregates alone.

### RE: Meaning of concrete mixer capacity.

Yes, what Ron said.

### RE: Meaning of concrete mixer capacity.

Looks like this. I can't quite work out how you get the concrete out...

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

### RE: Meaning of concrete mixer capacity.

Ron : what I wanted to say is that the capacity of the mixer ( at least here in Europe) is the volumetric capacity of the soft mix (not yet mixed). After mixing, the volume is approx 80%. After placing and vibrating, the final volume of concrete is 70% of the initial mix.
i.e. to have a final volume of vibrated concrete in place you need to mix 1.3 x final volume

White Paper - The Criticality of the E/E Architecture
Modern vehicles are highly sophisticated systems incorporating electrical, electronic, software and mechanical components. Mechanical systems are giving way to advanced software and electronic devices, driving automakers to innovate and differentiate their vehicles via the electric and electronic (E/E) architecture. As the pace of change accelerates, automotive companies need to evolve their development processes to deliver and maximize the value of these architectures. Download Now
White Paper - Model Based Engineering for Wire Harness Manufacturing
Modern cars, trucks, and other vehicles feature an ever-increasing number of sophisticated electrical and electronic features, placing a larger burden on the wiring harness that enables these new features. As complexity rises, current harness manufacturing methods are struggling to keep pace due to manual data exchanges and the inability to capture tribal knowledge. A model-based wire harness manufacturing engineering flow automates data exchange and captures tribal knowledge through design rules to help harness manufacturers improve harness quality and boost efficiency.

White Paper - Modeling and Optimizing Wire Harness Costs for Variation Complexity
This paper will focus on the quantification of the complexity related costs in harness variations in order to model them, allowing automated algorithms to optimize for these costs. A number of real world examples will be provided as well. Since no two businesses are alike, it is the aim of this paper to provide the foundational knowledge and methodology so the reader can assess their own business to model how variation complexity costs affect their business.
