msharief...the results, assuming all is well with the equipment as you have stated, are a function of the material properties, most notably the "hardness" of the aggregate.

Are your results excessive as compared to results by another laboratory? Are they excessive compared to results of an aggregate producer?

Please explain what you mean by "bad results".

 

[slowoldgit]

by bad results do you mean inconsistent, random, low or what? in comparison with those from aggregate suppliers or other labs?
