In detail and completely from the beginning, the method of conducting a granular gradient test for concrete aggregates
Granular gradation of concrete aggregate, whether coarse aggregate or fine aggregate
But when signing the accounts, it appears that there is a problem in the gradation and he does not know what is the reason for that
I assure you, dear technician, that the main problem lies in the method of taking the sample under test from its place
So you had to be good at sampling.
Without this test, the aggregate cannot be judged.
You, as a laboratory man, must have full experience in the method of conducting tests.
In this meeting, you can know what is the correct procedure and code and its application in order to judge whether the rubble is sound and good, or vice versa, and it is excluded from work.

I think this confirms that you are really an integrated artist.
