Effect of Using Egg Shell Powder and Microsilica partially in Place of Cement in M25Concrete

Abstract

Calcium wealthy egg shell could be a poultry waste withchemical composition nearly same as that of lime stone.Use of natural covering waste is also wont to replace cement byadding sure admixture which is able to improve theperformance. This experimental study aims to researchthe quality of egg shell powder as partial replacementfor cement (OPC 43) within the production of low-priced andlight weight concrete .This study investigates theperformance of concrete mixture in terms ofCompressive strength for seven days and twenty eight days, Flexuralstrength of beam twenty eight days and rending enduringness ofCylinder for twenty eight days severally of M-25 grade concreteat varied replacement levels of OPC by Egg shellpowder and a definite share of small silicon oxide as byweight of cement. Water-binder quantitative relation was unbroken constantfor all cases. These Concrete specimens were deep curedin water underneath traditional region temperature. On thebasis of result that partial replacement of cement in M-25concrete from Egg shell powder and small silicon oxide wasfound to extend altogether strength (Compressive, FlexuralTensile strength) and sturdiness of variationmix of concrete on all age compared to traditionalconcrete. Since it's economically viable thus its use ought tobe promoted.

Keywords: Egg shell powder, Micro silica, fine &coarse aggregates, cement ( opc 43 grade), flexuralstrength, compressive strength, split tensile strength.
