Nuke Gauge Help
(OP)
The engineer comp. I am working for told me that my field numbers for in place density are incorrect for density.
My daily standard and moisture are
2300 and 629
12 inch depth
My max Dens is 110.0 @ 12% for the project.
Wet.D 124.9
Water content pcf 13.4
Dry D 111.5
Water content% 12.1
I did the math on the set of numbers and are correct.
My employer told me that third are not the numbers he looks at.
The comp. looks at D. Count, M count and the ratios.
How is the Density count and Moisture count are
Calculated from the set of numbers above?
Thank you for your time.

RE: Nuke Gauge Help
You don't give the gauge manufacturer, but it would be a good idea to contact them and let them teach you how the gauge works. It is microprocessor controlled, and is generally not calculable to back into the counts. The counts are just that...they are counts of radioactive emissions from the extended rod back to the counter. The density of the material through which the emissions pass is correlated to how many particles are absorbed, reflected or make it through to the counter.

And yes...I remember looking up the counts on a chart! 1977+ for me.
RE: Nuke Gauge Help
I fondly remember the old charts, also trying to correct for not well understood chemical (gypsum was & is always fun). My memories go back to summer 1966, working for my father.
I wonder that anyone would insist on doing all the calcs. Too many opportunities for tech error. If I want to inspire tech error, I just insist on a sandcone. That can be a humbling experience for even the best.

Troxler gauge 3440
Daily DSC 1909
Daily MSC 684
Max Dem. 100 PCF
Max Moist 10.2
12 inch depth
1-Density count 686
2-Moisture count 104
3-WD Pcf 103.8
4-Water Pcf 7.0
5-DD 96.7
6-%M 7.3
The engineer told me that base on the
Numbers in lines 3,4,5 and 6
I could not have got the numbers in lines 1 & 2
Is there a math formula I can do to check this or a form chart? If so please let me know
Thank you.
