Abstract

In the last decades, the utilization of industrial waste like ground-granulated blast-furnace slag (GGBFS) has proven itself a great asset in the modern construction industry. Aiming at promoting the green housing initiatives, the present study focused on the study of the influence of GGBFS on the structural performance of self-compacting concrete (SCC). In the initial phase of the extensive experimental program, concrete cubes were prepared with the partial replacements of GGBFS (10%, 15%, 20%, 25%, and 30% with cement) and tested against the control mix in order to investigate the associated mechanical properties (compressive strength, tensile splitting strength, and flexural strength). At 20% GGBFS replacement, the optimum compressive strength was noted, and further addition of GGBFS caused a gradual decrease in the mechanical strength properties. This study further investigated the structural properties like axial load-displacement behavior and failure pattern of RC columns and flexural performance of RC slabs with and without the addition of GGBFS. SCC with 20% GGBFS demonstrated relatively better structural performance, causing the formation of smaller crack width/depth/length compared with the control mix. An empirical relationship was also proposed based on the experimental test results (in relation to the mechanical properties) in line with US and Indian standards code of practice.
