In this study, the behaviour of cementitious composites made with GGBS and carbon black powder was explored, as well as the usage of waste carbon black powder as a partial substitute for regular Portland cement. Investigated is the interaction of cement with various ratios of fine aggregate, carbon black powder, and water. Density and flow table tests are used to evaluate physical qualities, and SEM and EDS analyses are used to examine chemical components and microstructures. Experimental tests were performed on five proportionate samples, and mechanical characteristics were assessed. The ratio of carbon powder reaches 5% to attain valuable strength in cement mortar. The replacement cement's physical characteristics are comparable to ordinary portland cement. The results of the research demonstrated that using black powder from tyre waste as a contributing factor in cement mortars decreases the thermal behaviour of cement and enhances the polymerization of C-S-H gel compounds. To enhance the performance of concrete the optimum ratio of 25% GGBS and 5% tyre waste powder tested in compression, flexural, tensile and thermal tests are conducted. [ABSTRACT FROM AUTHOR] |
