20.500.12556/DKUM-70831 Relationship between the compressive and tensile strengths of lime-treated clay containing coconut fibres Povezava med tlačno in natezno trdnostjo z apnom obdelanih glin, ki vsebujejo kokosova vlakna The effects of coconut fibre on the mechanical characteristics of lime-treated clay are investigated in this study. The lime-treated clay specimens were prepared with a variety of coconut-fibre contents, i.e., 0.5%, 1%, 1.5% and 2%, in terms of the weight of dry soil. The stabilized specimens were tested at 7, 28 and 90 days after the treatment in order to observe the evolution of the mechanical resistance with time. The results of the unconfined compressive strength tests were used to determine the relationships between the compressive strengths and the indirect tensile strengths of the stabilized soil. Furthermore, the optimum percentage of coconut fibre mixed in the soil/lime mixtures was 1% of the dry mass and reinforcement at 90 days increases the peak compressive strength and the indirect tensile strength. Coconut-fibre inclusion changes the brittle behaviour of the lime-treated clay soil to give it a more ductile character. V članku so predstavljeni izsledki študije vplivov kokosovih vlaken na mehanske karakteristike z apnom obdelanih glin. Z apnom obdelani vzorci gline so bili pripravljeni z različnimi vsebnostmi kokosovih vlaken, in sicer z 0.5%, 1%, 1.5% in 2% teže glede na suho težo zemljine. Časovni razvoj mehanskega odpora utrjenih vzorcev je bil opazovan tako, da so bili preizkušeni po 7, 28 in 90 dneh od dneva obdelave z apnom. Rezultati preizkusa enoosne tlačne trdnosti so bili uporabljeni za določitev odnosa med tlačno trdnostjo in indirektno natezno trdnostjo z apnom utrjene zemljine. Nadalje je bilo ugotovljeno, da je optimalni delež kokosovih vlaken zmešanih v zmeseh zemljina-apno enak 1% suhe mase ter, da je takšna ojačitev v 90 dneh zvišala najvišjo tlačno trdnost in indirektno natezno trdnost. Dodajanje kokosovih vlaken spremeni krhki odziv z apnom obdelane gline v bolj duktilnega. coconut fibre lime compressive strength indirect tensile strength clay soil failure characteristics kokosova vlakna apno tlačna trdnost posredna natezna trdnost glinena zemljina karakteristike porušitve geotehnika true false true Angleški jezik Slovenski jezik Fakulteta za gradbeništvo, prometno inženirstvo in arhitekturo Univerze v Mariboru Znanstveno delo 2018-06-14 13:11:21 2018-06-14 13:12:23 2022-08-01 19:52:58 2019-07-11 18:21:17 2015 0 0 str. 49-57 št. 1 Letn. 12 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1854-0171 624.13 215987712 284356864 1854-0171 URN:SI:UM:DK:USONJ00D Acta_geotechnica_Slovenica_2015_Anggraini_et_al._Relationship_between_the_compressive_and_tensile_strengths_of_lime-treated_clay_contain.pdf Acta_geotechnica_Slovenica_2015_Anggraini_et_al._Relationship_between_the_compressive_and_tensile_strengths_of_lime-treated_clay_contain.pdf 1 9036829AEE77A0DC84B662844C5B097F af7d27de35514ea7df06164f977503e40fa89edfe224f4a0a6d3ebcaf156fb7e 09840d12-7c10-11eb-bb7a-00155d0001ca 20.500.12556/dkum/9e6380f4-f38a-4920-9353-53fd9fc3539b https://dk.um.si/Dokument.php?lang=slv&id=125708 http://fgserver3.fg.um.si/journal-ags/2015-1/article-5.asp 1 https://dk.um.si/Dokument.php?lang=slv&id=125709 Fakulteta za gradbeništvo, prometno inženirstvo in arhitekturo Acta geotechnica Slovenica 0 0 0
