▎ 摘  要

In this study, mortars with 250, 300, 350, and 400 dosages (amount of cement used in the production of 1m3 of mortar in kg) and a water/cement ratio of 0.85 were produced whose sizes are 4cm x 4cm x 16cm. In order to investigate the effect of graphene oxide on the physical and mechanical properties of mortar, samples containing 0.025%GO were produced instead of cement. In order to investigate the effect of DC on 300 dosage mortars; 15V, 20V, 25V, and 30V, stress intensities were applied for 24 hours through the DC power source while the mortars were in fresh. Within the scope of the study, the effects of the dosage on final setting time, flexural strength, and compressive strength were investigated. The mortars' internal temperature and surface moisture were measured every minute from the beginning of the hydration reactions. It was concluded that the optimum dosage is 300 in terms of improving the physical and mechanical properties of the mortars, and the optimum stress intensity is 25VIt was observed that when GO was added to the mortars, the internal temperature values of the mortars increased. It has been determined that the final setting time can be predicted by measuring the surface moisture in mortars. A noticeable improvement was observed in the microstructure of the mortars with the addition of GO and the application of DC.
