| الوصف: | U ovom istraživanju istražen je mogući sinergijski učinak upotrebe pepela drvne biomase (PDB) i recikliranih polimernih vlaka iz otpadnih guma (RTPF) na dugotrajno autogeno skupljanje i skupljanje uslijed sušenja, te je određena struktura pora uzorka morta s dodatkom PDB-a i RTPF-a. Rezultati pokazuju da primjena PDB-a i RTPF-a u mortovima utječe na strukturu pora, a time i na rezultate autogenog skupljanja. Kada se koriste PDB i RTPF, autogeno se skupljanje smanjuje, što nije slučaj za skupljanje uslijed sušenja. Najveće smanjenje autogenog skupljanja postignuto je dodatkom PDB-a i RTPF-a: autogeno skupljanje smanjeno je za 62 % nakon 90 dana u usporedbi s referentnom mješavinom. In this paper, the possible synergistic effects of fly wood biomass ash (WBA) and recycled tire polymer fibres (RTPF) on long-term autogenous shrinkage and drying shrinkage in mortar were investigated, and the pore structures of mortar specimens with WBA and RTPF were determined. The results showed that the use of RTPF and WBA has an effect on the pore structure of mortars and thus on the results of autogenous shrinkage. When WBA and RTPF were used, the autogenous shrinkage tended to decrease; however, this was not the case for the drying shrinkage. The greatest reduction in autogenous shrinkage was achieved by the addition of WBA and RTPF; autogenous shrinkage was reduced by 62 % after 90 days compared with the reference mixture. |
