Estimation Of Los Angeles And Micro Deval Abrasion Values For Gneiss And Granite Using Anfis Approach

Engineering Review : Međunarodni časopis namijenjen publiciranju originalnih istraživanja s aspekta analize konstrukcija, materijala i novih tehnologija u području strojarstva, brodogradnje, temeljnih tehničkih znanosti, elektrotehnike, računarstva i građevinarstva, 2020
Gneisses and granites mechanical properties knowledge such as the Los Angeles and Micro-Deval coefficients is very important for the engineer when designing and building civil engineering works. Laboratories test often performed to obtain Los Angeles and Micro-Deval values are expensive and time consuming.

Metodestudium av micro-Deval for alternative fraksjoner [PDF]

, 2022
Den europeiske standarden for bestemmelse av motstand mot slitasje ved bruk av micro-Deval, EN 1097-1, er under revisjon. I et høringsutkast for denne revisjonen, prEN 1097 1, er det beskrevet to nye metoder som omhandler testing på fine fraksjoner (0.25/5.6 mm og 0.2/4 mm i henholdsvis Annex D og Annex E) (CEN, 2021).

Evaluating the effect of mineralogy and mechanical stability of recycled excavation materials by Los Angeles and micro-Deval test [PDF]

, 2021
This paper presents the findings of the mechanical performance of recycled excavation materials (REM). The aim was to document the stable performance of REM and to suggest its suitability for unbound applications. Test operations were performed at different schedules with the Los Angeles (LA) and micro-Deval (MD) test machine.
