Fibers in concrete are one such advancement which offers a convenient, practical and economical method of overcoming many deficiencies in the properties of plain concrete. Fibers used in concrete help in reducing the crack formation and its propagation thereby increasing its toughness. Eggshell has the main component as Calcium Carbonate which is used as one of the main ingredients of Cement. So the use of eggshell instead of natural lime to replace cement in concrete can have benefits like minimizing the use of cement, conserving natural lime, and utilizing waste material. Carbon dioxide gets evolved during manufacturing of cement which is the main contributor of greenhouse effect that leads to global warming. So attempts are made by researchers to partially replace cement with other strength waste materials. The present study has been undertaken to analyze the effect of addition of glass fibers and eggshell powder in plain cement concrete and study its effect on the compressive of concrete. Experiments have been conducted on concrete cubes with partial replacement of cement with eggshell powder and also with addition of glass fibers. The testing has been done using varying percentage of eggshell powder by weight of cement. The first set of experiment was carried out by replacing 5, 10, and 15% of cement with eggshell powder. The compressive strength at 28 days was found out and compared with the conventional concrete. Further, the effect of addition of 0.025, 0.03, and 1% of glass fibers in combination with varying percentage of eggshell powder viz 5, 10, and 15% was assessed. The compressive strength at 28 days with addition of eggshell powder in combination with glass fibers was found out and compared with the conventional concrete.
