Rapid innovations in the ever-expanding area of the construction sector have turned into such a self-compacting concrete investigation (SCC). As a result of the effect on financial and ecological values, the importance of such innovation is expanding quickly. Many researchers have improved the efficiency of the present SCC using industrial materials. Pertinently, substituting cement with surplus material in the manufacture of concrete is environmentally sustainable. Eggshell has become one of the possible alternatives for cementitious material because it encompasses a compound of calcium. Such endeavour is primarily driven by the restriction of landfill sites and the desire to decrease the warming effect. This study describes the failure behaviour and cracks characteristics of SCC beams comprising eggshells under flexural assessment. In order to measure its compressive strength, an SCC mixture encompassing eggshells was developed and evaluated. The ultimate flexural strength and propagation of cracks were discussed for SCC beams tested under flexural using a various a/d (shear span to an effective depth) ratio. The SCC beams crack widths were also validated with Eurocode2. When loads are placed close to supports (lower a/d ratio), the results show that SCC beams can sustain a higher load with improved deflection control. The finding among all SCC beam assessments unveiled that the initial value of experimental crack width was significantly less than the 0.3mm maximum crack control limit delineated by Eurocode2 (EN 1992-1-1, 2004). Various kinds of crack characteristics have also been detected in SCC beam specimens marked as flexural, shear, and combination of shear-flexural cracks.
