| Popis: | U ovome istraživanju ispitani su upotreba betona s udjelom zgure iz visoke peći (eng. blast furnace slag - BFS) u postotku od 15, 20, 25 i 30 % u odnosu na masu cementa, kao cestovnoga kolnika na tlima slabe nosivosti te odnos koristi i troškova u njegovoj upotrebi. Pripremljeni uzorci betona podvrgnuti su fizikalnim i mehaničkim ispitivanjima prateći njegovanje različitoga trajanja, čime je utvrđeno da se čvrstoća uzoraka kojima je dodan BFS povećala te da je bila najveća kod uzoraka s udjelom BFS-a od 20 %. Štoviše, prema metodi projektiranja AASHTO 1993, dokazano je da se debljina betonskoga kolnika kojemu je dodan BFS smanjila za 1,58 do 3,38 %, a da su se troškovi smanjili za 5,59 do 10,30 %. In this study, the usability of concrete containing blast furnace slag (BFS; 15, 20, 25, 30 wt.%) as road pavement on soils with weak bearing strength and the corresponding benefit–cost relationship were investigated. The prepared concrete specimens were subjected to physical and mechanical tests following different curing times, and it was determined that the mechanical strength of the BFS-added specimens increased and peaked at the BFS content of 20 %. In addition, according to the AASHTO 1993 design method, it was determined that the thickness of the BFS-added concrete pavement decreased by 1.58 % to 3.38 % and the cost was reduced by 5.59 % to 10.30 %. |
