Analyses of cement mortars containing reclaimed asphalt pavement by using DTA/TG and FTIR

Abstract

Reciklirani asfaltni kolnik (RAP) koristi se u istraživanju kao reciklirani materijal za proizvodnju cementnog kompozita. Za proizvodnju uzoraka u cement je dodano 5 %, 10 % i 15 % RAP-a. TG/DTA analiza, izvedena nakon određivanja savojne čvrstoće, pokazala je da se minimalan gubitak mase uzorka javio u uzorcima s 5 % RAP-a pri kontroliranim uvjetima. Najveći gubitak mase iznosio je 11,8 %, a druga najviša vrijednost iznosila je 8,2 % za uzorke koji imaju 15 % aditiva C i koji su se njegovali pomoću otopine MgSO4.The reclaimed asphalt pavement (RAP) is used in the study as a recycled material for the production of cement composite. 5 %, 10 % and 15 % of RAP was added to the cement to produce samples. TG/DTA analyses, performed after flexural analyses, revealed that the minimum mass loss occurred in the samples with 5 % RAP additive at stable conditions. The highest mass loss was 11.8 %, and the second highest value amounted to 8.2 % for samples with 15 % of C additive cured in MgSO4 environment
