Abstract
The findings of an experimental investigation of the mechanical characteristics of plain and eggshell powder (ESP) concretes, both with and without steel fiber, are presented in this work. Using eggshell powder instead of cement is a feasible alternative for creating environmentally friendly concrete. At the same time, it improves the disposal of eggshell, which is commonly discarded as household waste and ends up in landfills. The several benefits of steel fiber reinforced concrete (SFRC) are that it prevents macro crack propagation, prevents macro cracks by increasingly of macroscopic size, improves ductility and residuary strength since of the initials cracks form, and has a high degree of toughness. To develop of the eggshell powder included steel fibre reinforced concrete mixtures, Ordinary Portland cement (OPC 43 grade) was partially replacement with ESP 0%, 5%, 10% and 15% by weight of the total binder content. The steel fibers were incorporated into the mixture at volume fractions of 0.5%, 1.0%, and 1.5%. Hook ended steel fibres with lengthaspect ratios of 50 were to create fibre reinforced concrete. On the compressive, flexural, splitting, and bonding strengths of the concretes, the effects of ESP and steel fiber reinforcement were examined. Additionally, examinations of the eggshell powder and cement's microstructure using XRD and SEM were performed. The tests were performed after 7, 14, and 28 days of the curing period. The optimum increases in the mechanical properties of concrete produced 10% eggshell powder and with 10% eggshell powder and 1% steel fibre (SF).
