Concrete mixer laboratory type

24May

Concrete mixer laboratory type includes properties tests, quality tests, power motor inspects and operating defecting. Performance Attributes as Indicators of Efficiency is one of test specifications for cement mixers.

How to judge Performance Attributes as Indicators of Efficiency affecting concrete mixer?
Since the macroscopic properties of concrete are affected by its composition, it is conceivable that the homogeneity of the concrete produced could be monitored by measuring the performance of specimens prepared with concrete taken from different parts of the mixer or at different times during the discharge. Properties that are often considered are • workability of the fresh concrete as defined by the slump;
• density of the concrete;
• air content;
• compressive strength.

Some disadvantages of this method for concrete mixer
A disadvantage of this method is that it is indirect. It does not directly show that the concrete is homogeneous but only assumes that any potential inhomogeneity affects the properties considered. In addition, it is possible that either the measurement methods selected are not sensitive enough to local changes in composition, perhaps because the samples are too large, or that the properties selected are intrinsically not affected by inhomogeneity.
The consistency in the properties is a useful guide but not a definitive indicator of product homogeneity. It can give a false sense of security about the mixing method used.

Concrete mixer laboratory type is also operating in international or national agent to ensure concrete mixer quality and concrete mixer performance.
