German term

LAK

German to English Tech/Engineering Geology
This is an appraisal of a construction site to determine the different grades of sand and gravel present.

"LAK" appears in a table in the unit of measure column next to "Abrasivität".

Does anyone know what we would say in English as a unit of measure for abrasiveness?
Proposed translations (English)
5 LCPC abrasion coefficient (LAC)
4 +3 LAC / ABR

Likely meaning Germans are more professional than the English

Johannes Gleim May 21, 2023:
@ Kim Completely wrong! I was sure and proved that "LAK" is a German term used by German scientists and that English-speaking specialists can translate the term. Nothing more. Please do not falsify or misconstrue my statements.
And your 2nd entry does not add any useful information not contained in my references.

Herr Gleim wrote: "LAK" is certainly a German abbreviation and it is likely that more German professionals know its meaning than English professionals." This makes no sense. You're saying German translators should be preferred for translations into English? Same thing for German to French, Spanish, Italian?:
Kim Metzger May 20, 2023:
Abrasivity The LCPC Abrasivity Coefficient (A BR or LAC) can be used as a measure for both the abrasivity of the material and the influence of the grain size. https://www.researchgate.net/publication/285524169_Determini...
Johannes Gleim May 20, 2023:
@ Holly Please change the target audience! "LAK" is certainly a German abbreviation and it is likely that more German professionals know its meaning than English professionals. After clarification of the term, English speakers could also contribute to the translation and/or search of the English abbreviation (if requested).

In order to facilitate the search, you are invited to add some or all other headers in the table, or the specific entries under "LAK" with units (if any).

LCPC abrasion coefficient (LAC)

Abrasivität kaum abrasiv – abrasiv (LAK 50 - 500 g/t)
https://www.google.de/url?sa=t&rct=j&q=&esrc=s&source=web&cd...

Der LCPC-Abrasivitätskoeffizient (LAK) ist der Abrieb, genauer der Gewichtsverlust eines Stahlflügels in einem Behälter mit 500 g gebrochenem Festgestein der Körnung 4 – 6,3 mm (Thuro et al. 2006)
https://docplayer.org/81783119-Klassifikation-der-abrasivita...

Der am Laboratoire Centrale des Ponts et Chaussées entwickelte LCPC-Abrasivitätsversuch
wird derzeit im deutschsprachigen Raum üblicherweise zur Untersuchung der Abrasivität von Lo-
ckergestein herangezogen.
:
Was die Aussagekraft des LCPC-Abrasivitätskoeffizienten für u.a. die Verschleißprognose betrifft, so existiert erheblicher Interpretationsspielraum, wie die Gegenüberstellung der qualitativen Abrasivitäts-Bezeichnungen aus der Fachliteratur in Tabelle 1 belegt.
Tabelle 1 Gegenüberstellung der Abrasivitäts-Klassifizierung nach Büchi et al. [4] und nach Thuro [13], [14]
|Abrasivität LCPC-Abrasivitätskoeffizient | Abrasivität
|nach Büchi | Abr [g/t] | LAK [g/t] | nach Thuro |
|Sehr schwach | 0 – 500 | 0 - 50 nicht abrasiv |
| | | 50 - 100 | kaum abrasiv |
| 100 - 250 | schwach abrasiv |
| 250 - 500 | abrasiv |
https://publik.tuwien.ac.at/files/PubDat_189310.pdf

That explains LAK right now, it is the LCPC-Abrasivitäts-Koeffizient
Now for the translation:

The correlation between LCPC abrasion coefficient (LAC) and the percentage of abrasive components (Thuro et al. 2006), Mohs' hardness values (Hashemnejad et al. 2012), EQC values (He et al. 2016; Hashemnejad et al. 2016), and quartz content (Düllmann et al. 2014) has been reported.

LAC / ABR

LAK = LCPC Abrasivitäts-Koeffizient

e.g. here https://docplayer.org/81783119-Klassifikation-der-abrasivita... "Der LCPC-Abrasivitätskoeffizient (LAK) ist der Abrieb..."
or here: https://www.wille-geotechnik.com/de/abrasive-test-machine-lc...


LCPC test is called that after the lab that developed it: https://www.sciencedirect.com/science/article/abs/pii/S08867...

Also suggests ABR https://onepetro.org/ARMACUSRMS/proceedings-abstract/ARMA07/... "... which was developed by the Laboratoire Central des Ponts et Chaussées in the 1980ies. The LCPC Abrasivity Coefficient (ABR or LAC) can be used ... "
