Determining the LCPC abrasivity of sand and gravel in project of Hanoi pilot light metro line, section Nhon – Hanoi railway station

Conference paper
Part of the Lecture Notes in Civil Engineering book series (LNCE, volume 62)


For underground construction, the abrasivity of sand and gravel need to determine because it affects the tool wear and excavation performance. The paper represents the abrasivity properties of sand and gravel distributed in Nhon – Ha Noi station Metro line. The abrasivity parameters include LCPC Abrasivity Coefficient (LAC) and the LCPC breakability coefficient (LBC). For determining these parameters, the apparatus LCPC was designed in the laboratory of LAS -XD 442 in order to meet the requirement stipulated of the French Standard P18-579 (2013). A lot of abrasivity tests were carried out on sand and gravel. The results of experiment showed that, sand can be classified LAC. LAC varies from 52 g/l to 1683.45 g/l, abrasivity of sand ranges from not very abrasive, slightly abrasive to extremely abrasive. For gravel, besides the LAC, the LBC was also determined. LBC of gravel varies between 45 and 55%. Gravel can be classified as extremely to medium breakability. The results also indicated that the factor affecting the sand and gravel abrasively is particle size (gravel content, sand content).
