INVESTIGATION OF THE USE OF ENVIRONMENTALLY FRIENDLY BINDERS IN THE PRODUCTION OF SIFCON MATRIX

In this study, blast furnace slag (BFS) and fly ash (FA) which are industrial waste were used as binders instead of cement used in the production of SIFCON slurry. For this purpose, control mixture and alkali activated mixtures were prepared in four different series as 100% FA, 50% FA- 50% BFS, 100% BFS. Na ratios of alkali activators used in mixtures were 4%, 6% and 8%. Viscosity, hardened unit weight, compressive strength, flexural tensile strength and ultrasonic pulse velocity tests were performed on the samples. The viscosity values of the alkali-activated. BFS mixtures were similar to the control mixtures as the spindle rotation speed increased. The compressive strength values of alkali activated BFS samples were higher than control samples and alkali activated FA samples. The flexural tensile strength and ultrasonic pulse velocity values of alkali activated samples were lower than the control sample. As a result of the study, it has been seen that alkali-activated BFS mixtures can be used in the production of SIFCON slurry. The use of industrial wastes as a binder in SIFCON production will contribute to reducing natural resource consumption. recycling resources, conserving energy and protecting the environment.
