Karakteristike trajnosti betona s bakrenom zgurom i s dodatkom letećeg pepela ; Durability characteristics of copper slag concrete with fly ash
U radu se razmatra trajnost kombinacije letećeg pepela (FA) i bakrene zgure (CS) u betonu. Provedeno je eksperimentalno istraživanje o pokazateljima trajnosti kao što su upijanje vode do zasićenja, poroznost, koeficijent upijanja vode, sorptivnost, ubrzano ispitivanje prodora kloridovih iona te ispitivanje alkalnosti (pH). Ispitana je i mikrostruktura betona te je provedena kvantitativna analiza nakon 90 dana pomoću pretražnog elektronskog mikroskopa i energijski razlučujuće rendgenske spektrometrije. Dobiveni rezultati pokazuju da se primjenom kombinacije FA i CS poboljšavaju svojstva betona. ; The durability of the combination of Fly Ash (FA) and Copper Slag (CS) in concrete is studied in the paper. Experimental study was conducted to determine durability properties such as saturated water absorption, porosity, coefficient of water absorption, sorptivity, rapid chloride ion penetration test, and Alkalinity (pH) test. The microstructure of concrete was tested and quantitative analysis was carried out at the age of 90 days by the scanning electron microscope and energy dispersive X-ray. The results show that concrete properties are improved by the combined use of FA and CS.
